The variable being regridded is daily rmse will be a 2-dimensional array with dimensions (ktime, nlev) [(120, 28)]. It is actually scalar and definitely not 2-dimensional. 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. For geo-referenced data, xo is generally the longitude array. A multi-dimensional array or scalar value equal to the mean of the distribution (-infinity to +infinity). Interpolates from high resolution rectilinear grids to low resolution rectilinear grids using local area averaging and retains metadata. Given wind components u and v, uv2vrF computes the vorticity and returns it as an array with the same dimensions as u and v (values will be in ascending latitude order). NewList: Create a list (type variable). For geo-referenced data, xi is generally the longitude array. No interpolation performed on these arrays An Introduction to Three-Dimensional Climate Modeling W. LV Because a1 and a2 are pointers, you need an array of pointers to contain them: const char *b[] = { a1, a2 }; // char *b[2] = { a1, a2 } would also work So what you need isn't really an array of arrays, but just a standard single one-dimensional 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 In the above, notice that NCL arrays are initialized by bracketing the data with the array designator characters "(/" and "/)". linint2pts (fi Further assume lon2d and lat2d are 2D arrays of size N x M associated with some arbitrary grid. XLAT and Xlon are 2D. lat2d. In this case, x should not include the cyclic point.

Example 6. htm at master · tfoterye/NCL_help fatal:linint2: If xi is not one-dimensional, then its leftmost dimensions must be the same as the average_op_ncl : dim_avg_n over dimension(s): u_v fatal:linint2: The rightmost dimensions of fi must be nyi x nxi, where nyi and nxi are the lengths of yi and xi respectively Note: for an integer array, any values equal to 0 also evaluate as False, so the above expression could also be accomplished with: x = where(oro, a+273. Have a question or problem with installing NCL? Subscribe to ncl-install and then email your question to ncl-install@ucar. The rightmost dimensions will be the same as. A two-dimensional array. 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. Creates an array of equally-spaced integer, long, or int64 values. Value at which to start. This example returns the interpolated values to the original one-dimensional array. I write_csv_2. 8 : Thu Sep 09 2010 - 05:56:39 MDT [1] As noted in the documentation, linint2_points Interpolates from a *rectilinear grid* to a user specified set of points using bilinear interpolation. xi (numpy.

Where can I download NCL? See the NCL download page for full instructions. Description Creates a nice plot of the joint probability array created by the pdfxy function. 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 are two-dimensional. linint1, linint2, ftsurf, [if global, shperical harmonic regriders], if the input is on a curvilinear grid, perhaps rcm2rgrid, rtc [untested] function congrid (q, dimout[*],cyclic:logical, opt:integer) resizing 2-dimensional array X from X[200, 300] to > X Re: NCL function "linint2_points_Wrap" This message : [ Message body ] [ More options ] Related messages : [ Next message ] [ Previous message ] [ In reply to ] [ Next in thread ] [ Replies ] The array you are inputting is rank 4 with dimensions (ncl_join,time,lat,lon) [ncl_join | 25] x [time | 12] x [LAT | 224] x [LON | 256] [2] The documentation for the month_to_seasonN states the following: *xMon* A one-, three-, or four-dimensional array (*xMon*(time) or *xMon*(time,lat,= lon) or *xMon*(time,lev,lat,lon) of any numeric type.
