A multi-dimensional array to be interpolated. htm at master · tfoterye/NCL_help From: jonathan meyer <tallj03_at_nyahnyahspammersnyahnyah> Date: Wed Jul 27 2011 - 12:27:54 MDT Hello all, I am attempting to regrid wrf output variables (specifically u and v wind components on 4 standard upper levels; 850, 700, 500 and 250mb) to the A two dimensional array is returned that contains both the Gaussian latitudes (first dimension) and the Gaussian weights (second dimension). If yi is a multi-dimensional array, then each nyi subsection of yi must be ncl releases. You signed out in another tab or window. The resulting gaussian latitude array can be created using latGau. The rightmost dimension (call it nxi) must have at least two elements, and is the last (fastest varying) dimension of fi. fi An array of one or more dimensions. html即可。二爷整理，版权归NCAR所有。 - NCL_help/linint2_points. If user-defined NCL 帮助本地版，可以直接clone到本地，打开index. lat Test if all non-missing elements of an array are identical. ncl: Another example of using linint2_Wrap to perform a bilinear interpolation from a (180,360) regular grid to a slightly different resolution (192,288) grid. local_max_1d: Determines the relative maxima for a 1-dimensional array. If xi is multi-dimensional, then its dimensions must be the same size as fi's dimensions. If it is one-dimensional, its length (call it nxi) must be the same as the dim-th dimension of fi. They must be the same length as the rightmost dimension of z. latGau, NCL 帮助本地版，可以直接clone到本地，打开index. linint2_points_Wrap can be used to interpolate from a standard grid (fi) where the xi and yi arrays are monotonically increasing 1D arrays, to an arbitrary grid where the output coordinates are fi (xarray. The rightmost dimension (call it nxifi A two-dimensional array that specifies the latitude locations of fi. > > My code is included below. You switched accounts on another linmsg_n, linint1, linint2 Examples Example 1 This example returns the interpolated values to the original one-dimensional array. The third is an assignment of a _FillValue. y. (The default missing value for the input type will be used if no missing value is attached to the input array). In some cases, xi can bea multi-dimensional array (see next paragraph). If the rightmost two dimensions represent latitude and longitude, then they will be ordered longitude x latitude , which means you need to transpose them before plotting. iz is a file variable. The error message is telling you exactly what the error is. fi A multi-dimensional array to be interpolated. If xi is a multi-dimensional array, then each However, if you pass in your airw array: fo = linint2 (airw&lon,airw&lat,airw, True, LON, LAT, 0) You will get the referenced error message as time is the rightmost dimension in [1] As noted in the documentation, linint2_points Interpolates from a *rectilinear grid* to a user specified set of points using bilinear interpolation. regrid_14. If it is not explicitly provided, NCL will use a default value. e. The two rightmost dimensions (nyi x nxi) are the dimensions to be used in the interpolation. So replace iz with P1. The end points will be left as NCL contributed. ncl functions (lat/lon functions) NCL Home > Documentation > Functions > Array query, Lat/Lon functions getind_latlon2d Returns the indices (subscripts) of two-dimensional latitude/longitude arrays closest to a user-specified latitude/longitude An array of dimensions N x NumXOut x NumYOut, where N represents all but the last (rightmost) dimension of z, containing the interpolated functional values at the points specified by xo and yo. See Also "B" example:, values within (/. shtml. Returns. Finds the indices (subscripts) of two-dimensional lat2d/lon2d arrays closest to each lat/lon coordinate pair. Exact quote from linked page is: The ReDim statement is used to size or resize a dynamic array that has already been formally declared using a Private, Public, or Dim statement with empty parentheses (without dimension subscripts). It may be monotonically increasing or decreasing. DataArray or numpy. It must be the same dimension size (call it mx) as the right dimension of z. local_min_1d: Determines the relative minima for a 1 Coordinates associated with the right dimension of the variable z. B is 3D, not 1D with three elements. lon rgrid2rcm_Wrap, rcm2rgrid, rcm2points, linint2, linint2_points, ESMF_regrid Examples Example 1 Interpolate from If xi is multi-dimensional, then its dimensions must be the same size as fi's dimensions. By default the returned values are of type double. That is what the message is telling you. Previous message: [ncl-talk] fatal:No coordinate variable exists for dimension (lat) in variable (modvar_pd_elnino) Next message: [ncl-talk] Discrete Color Bar Messages sorted by:. This isn't exactly intuitive, but you cannot Redim an array if you dimmed it with dimensions. Also note that you do not need to A two-dimensional array that specifies the longitude locations of fi. fi One-dimensional arrays containing the longitudes and latitudes associated with the z values. Return value. Because this array is two-dimensional it is not an associated coordinate variable of fi. For geo-referenced data, xo is generally the longitude array. The variable being regridded is daily The dimension numbered "0" is referred to as the first dimension of the array, the dimension numbered "1" as the second dimension, and so forth. If it is one-dimensional, its length (call it nxi) must be the same as the rightmost (fastest varying) dimension of fi. The longitude order must be west to east. The rightmostnxi geocat. A multi-dimensional array of the same size as fi except that the rightmost dimension sizes have been replaced by the sizes of lat1d and lon1d, An array that specifies the X coordinates of the fi array. If it is one-dimensional, itsnxifi. The new function and See example one for the creation of the longitude array. html即可。二爷整理，版权归NCAR所有。 - tfoterye/NCL_help An array that specifies the X coordinates of the fi array. The input grid may be cyclic in the x-direction. isscalar: Returns True if the given argument is a scalar (rank one and size one). An array that specifies the X coordinates of the fiarray. See Also There are numerous other latitude/longitude functions. It must be strictly monotonically increasing or decreasing, and can be unequally spaced. Most frequently, this is a 1D strictly monotonically increasing array that may be unequally spaced. In other words, instead of dim invoices(10,0) A one-dimensional array that contains latitudes. The leftmost dimension is the slowest varying, and the rightmost dimension is the fastest varying (i. In NCL V6. It must be the same dimension size (call it ny) as the left dimension of z. It must be monotonically increasing, but may be unequally spaced. isMonotonic: Check a one dimensional array to see if it is monotonic. Assume ntim1=100 and ntim2=1, and that T1 is a 4D array with dimensions ntim1 x klev x nlat x mlon and dp is an array with dimensions ntim2 x klev. /) are dimensions, not array values. Presumably you want to use a data variable from inside the file. "C" example: there are three arguments to the new funtion. html即可。二爷整理，版权归NCAR所有。 - tfoterye/NCL_help A two-dimensional array that specifies the longitude locations of fi. > Hi Sri, The error message is telling you what the issue is: fatal:linint2: The rightmost dimensions of fi must be nyi x nxi, where nyi and nxi are the lengths of yi An array that specifies the X coordinates of the fi array. The rightmostdimension (call it nxi) must have at least two elements, and isthe last See more linint2_points can be used to interpolate from a standard grid (fi) where the xi and yi arrays are strictly monotonically increasing 1D arrays, to an arbitrary grid where the output coordinates In some cases, xi can be a multi-dimensional array (see next paragraph). edu Sun Sep 27 21:09:44 MDT 2015. Description ----------- – Interpolates RCM (Regional Climate Model), WRF (Weather Research and Forecasting) and NARR (North American Regional Reanalysis) grids to a rectilinear grid. . Note that ntim2 is a degenerate dimension. Description. Most frequently, this is a 1D strictly monotonically increasingarray that may be unequally spaced. Coordinates associated with the left dimension of the variable z. V = cru1990 re: fo = linint2(airw&lon,airw&lat,airw(time|:,lat|:,lon|:), True, LON, LAT, 0) Which gives an error: warning:linint2: xi, yi, xo, and yo must be monotonically > In trying to use linint2, NCL complains that my longitude array is 2D and > it wants 1D (though the documentation says 2D should be okay). 3. This illustrates that NCL array syntax must be aware of _FillValue. fi. Must be monotonically increasing. linint2_points (fi, xo, yo, icycx[, msg, meta, xi, yi]) linint2pts This argument allows a user to use a missing value scheme other than NaN or masked arrays, similar to what NCL allows. The rightmost two dimensions (latitude, longitude) are the dimensions to be interpolated. If a missing value is encountered at any of the two rightmost dimensions, then the result will be set to q@_FillValue (opt = 1). lon2d rcm2points_Wrap, rgrid2rcm, rcm2rgrid, linint2_points, linint2_points_Wrap, ESMF_regrid Examples Example 1 Interpolate to two locations In some cases, yi can be a multi-dimensional array (see next paragraph). A one-dimensional array that specifies the Y coordinates of the return array. A one-dimensional array that contains longitudes. The rightmost dimension (call it nyi) must have at least two elements, and is the second-to-last dimension of fi. Two-dimensional array of size ny x mx containing the iz is a file variable. Step-by-step illustration based on a user question. The rightmost two lat An array that specifies the X coordinates of the fi array. That would be P1 in your code. lon. An array, whose rightmost dimension is the same length as zlon and zlat, containing the rmse will be a 2-dimensional array with dimensions (ktime, nlev) [(120, 28)]. 0, so unfortunately I cannot try the new ESMF functions. Contribute to yyr/ncl development by creating an account on GitHub. linint2# geocat. 0. A two dimensional array containing index subscripts corresponding to nearest lat2d/lon2d point. Specifically, you are specifying -95 and -87 for your longitudes that go into lon_cx. Note: If it is desired to go from a low resolution to a high resolution grid use bilinear resolution (linint2, linint2_Wrap) or, possibly the An array that specifies the X coordinates of the fi array. The interpolation is first performed in the NCL 帮助本地版，可以直接clone到本地，打开index. It is actually scalar and definitely not 2-dimensional. A multi-dimensional array of the same size as fi except that the rightmost dimension sizes have been replaced by the sizes of lat1d and lon1d, respectively. fi [ncl-talk] fatal:No coordinate variable exists for dimension (lat) in variable (modvar_pd_elnino) Dennis Shea shea at ucar. z. comp. Hi Manda, Make sure that the range of your lon/lat arrays match the range of your lon_cx/lat_cx arrays. , arrays are stored in the "row x column" format familiar to C programmers). As far as I (linint2_Wrap) is (2), (1) dimensions were expected. The latitudes should proceed from south-to-north.
