Extraction of variable values from single point. Is my process correct?

Added by Marco Pesce almost 9 years ago

Hello everyone,

My name is Marco and I am a PhD student from University of Venice, Italy.

I have netcdf files of Europe but I only need one point, which I want to extract in .dat format. I am writing to you because I am encountering difficulties in understanding if the procedure I adopted is correct or not. In other words, I don't know if the values I have extracted are those of the exact coordinates I need.

My Point: Longitude: 12.176, Latitude: 45.59, Projected Coordinate System: Monte_Mario_Transverse_Mercator, The point is located in Italy next to the Lagoon of Venice.

NetCDF File Information obtained from cdo sinfo input.nc: Grid Coordinates: curvilinear, lon:-44.5939 to 64.9644 degrees_east, lat: 21.9878 to 72.585 degrees_north, 174688 points (424x412).

String I used to extract my data: cdo -outputtab,date,lon,lat, value -remapnn, lon=12.176_lat=45.59 input.nc > output.dat which converted form curvilinear (424x412) to lonlat(1x1) grid.

It works but, is the process correct? If possible I would like to understand how I can check the correctness of what I did regarding longitude and latitude.

Thank you very much for your help.

Best,
Marco Pesce
