ERA5-Land GRIB files: latitude and longitude bounds

Datasets and Usage C3S - Datasets and Usage

Hi everyone,

I’m checking the coordinates in ERA5-Land GRIB files and noticed that, for some variables (evaporation from bare soil, evaporation from open water surfaces excluding oceans, evaporation from the top of canopy and evaporation from vegetation transpiration), longitude values range from 328 to 355, although I requested the following bounding box:

North, West, South, East\] = \[43, −32, 31, −5

The study area covers mainland Portugal, Madeira and the Azores.

Are these longitudes simply expressed using the 0–360° convention, equivalent to −32° to −5°?

Is it expected that different variables use different longitude conventions?

Thanks for your help!
