GRACE-based drought indicator datasets

[Ohm-Np]

Dataset:

GRACE-based shallow groundwater drought indicator	Spatial Coverage	Global
Spatial Resolution	0.25 degrees
Temporal Coverage	2003-Feb to Present
Temporal Resolution	Weekly updates
Unit	percentile
Inference	percentile describes current wet or dry conditions showing the probability of occurrence - with lower values meaning dryer than normal, and higher values meaning wetter than normal

I already created function (API connecting to nasagrace) to download these rasters. Of which time period you need the data @Jo-Schie? Should I download all or may be yearly by choosing specific dates of the year?

Note: Size of one raster file is ~900 kb

Hi Om. Great. We will need all data for all years. I will have to come up with a concept still on how to aggregate the values afterwards but for the moment I would suggest you just create mean values for all weeks. Please also store at least some of the input data. I would like to look at it afterwards.

Please find the results here: "../../datalake/mapme.protectedareas/output/polygon/drought_indicator/gws_supportedPAs.csv" "../../datalake/mapme.protectedareas/output/polygon/drought_indicator/gws_allPAs.csv"

and the original rasters here: "../../datalake/mapme.protectedareas/input/drought_indicator/"

I have added a new column called date to read the data easily, sample result:-

WDPA_PID       date                  name         value
6675       2003-02-03     mean_percentile      86.57270
478068     2003-02-03     mean_percentile      43.94059
478085     2003-02-03     mean_percentile      96.69246
478089     2003-02-03     mean_percentile      63.06751
478101     2003-02-03     mean_percentile      51.89230
478130     2003-02-03     mean_percentile      69.02441
