Trouble with Sellonlatbox Longitude Inputs

Hello everyone.

I have what I hope is a simple problem to solve. I would like to extract data for a box ranging from the Gulf of Mexico (-97 lon) to the end of the Mediterranean Sea (35 lon). I have read the documentation but still cannot get the desired output file.

I have tried the following inputs:

1) cdo sellonlatbox,-97.77,35.12,0,51.04 input.nc output.nc (Extracts all longitudes around the globe but can't figure out why)
2) cdo sellonlatbox,262.23,395.12,0,51.04 input.nc output.nc (Starts at -97.77 but stops at 360/0, which I assume is the limit)

I have attached screenshots, as well as the coordinate information of my file (0 - 360). Any help or advice would be greatly appreciated!

Hi Neil,

your data is curvilinear with a projection which maybe is the cause for the problem.
Can you upload the data? One timestep and one variable is enough.

The longitude values are going from 0.0147311 to 359.996 degrees and you have to set the longitude values for sellonlatbox as

cdo sellonlatbox,262.23,395.12,0,51.04 sample.nc outfile.nc
