There’s probably a
simple solution to this, but it’s escaping me, so I thought I’d try
posting. I’ve managed to successfully load in my NetCDF files using
the NetCDF API 2.2, and am now trying to extract a subset of data from them –
exactly what the MultiArrayProxy and ClipMap functions provide (see: http://www.unidata.ucar.edu/support/help/MailArchives/netcdf/msg00043.html)
, but I’m at a loss as to how to generate a MultiArray from the original
NetCDF data. I’ve come across examples of how to generate
MultiArrays from scratch, and I can extract Arrays from my data, but not
MultiArrays. It also looks like MultiArrays are possibly an older feature(?),
so there may be a better, more up-to-date way that I’m missing. These are my variables: [ float
Longitude(Longitude=2294); :units =
"degrees_east"; :valid_range =
98.84f, 282.28f; // float :step = 0.8f;
// float :standard_name
= "longitude"; :axis =
"x"; , float
Latitude(Latitude=1362); :units =
"degrees_north"; :valid_range =
-20.057325f, 65.86738f; // float :step = 0.8f;
// float :standard_name
= "latitude"; :axis =
"y"; , int layer(layer=20); :units =
"layer"; , float uvel(layer=20,
Latitude=1362, Longitude=2294); :_FillValue =
1.0E34f; // float :units =
"ms-1"; :standard_name
= "eastward_sea_water_velocity"; :long_name =
"eastward_sea_water_velocity"; :unit_long =
"meter_per_second"; :missing_value
= 1.0E34f; // float :valid_range = -229.31992f, 80.65831f; //
float ] And I’m
looking to subset uvel based on Latitude, Longitude and layer (e.g. if Lat
ranges from 20-40, Lon from 0-10 and layer from 0-10, I’d like to extract
the uvels for 25-35, 3-7 and 5-8 respectively). Any constructive advice,
examples or links would definitely be appreciated. Thank you! J |
