# EarthMap - downloaded GeoTIFFs of ECMWF layers do not contain raw data

Asked by francescaforest on 2024-06-18

Hello,

I'm trying to obtain ECMWF climate anomalies layers (mean temp., precipitation etc.) using the Download button in the layer legend. I need the raw data for further processing in QGIS, so I selected the "Download GeoTIFF" option. However, when I load the resulting file in QGIS, what I get is an RGB image reproducing the same colors as in the EarthMap interface, instead of a single band raster with anomalies values as expected. On the contrary, I am able to obtain the raw data (using the same procedure) for Heat Stress Days, Heatwave Occurrence Days and Aridity Index.

Am I doing anything wrong, or is this a bug in the export code?

Thank you in advance for your attention.
