Respected @swolny @megannissel @jdouglass @jesseG,
Please is the ready to use PAWC prepared my NATCap has a multiplying factor? I am curious about the unit(mm/mm) or (m/m) or (mm/m). For my study area, the values are from 0 to 0.006375 and my precipitation ranges from 1200 to 1450mm. Using the 0 to 0.006375 makes my Z factor not sensitive to water yield? Any help regarding the usage of the NATCap prepared PAWC as their is no documentation stating the unit. Thank you

Hi @ADIGUN -
Well shoot, you’re right that the values in this layer don’t look correct. Apologies for letting that go unnoticed. We are investigating the methods we used, and will post a corrected layer when we have a chance, but I don’t know when that will be.
If you look at the metadata (YML) file that we provide on DataHub for all of our layers, it states the units for PAWC as ‘decimal fraction’.
If you want to create your own PAWC layer from SoilGrids 2017 AWC data (which is what the DataHub layer is based on), you can follow the instructions provided in the User Guide.

Respected @swolny
Thank you for kind response and acknowledging my observation.
Best regards,

Hello @ADIGUN ,
The PAWC layer has been corrected and posted on the data hub, and it is now available here: Plant Available Water Content - Global Dataset - Dataset - NatCap Data Hub
Thank you again for letting us know about this layer, and please let us know if you have any other questions about this or any other layer on the Data Hub!
