I have daily rainfall data in milimeters in GeoTIFF format with naming convention chirps_YYYYMMDD.tif (example chirps_20100101.tif), and I also have 1 raster of dry-spell with name dslr_chirps_20091231.tif and both raster have same spatial resolution and extent.
Then I would like to calculate dry-spell for 1 Jan 2010, IF(rainfall>1,dslr=0,dslr+1). Using raster calculator I can use this formula: Con("chirps_20100101.tif" > 1, "dslr_chirps_20091231.tif" == 0, "dslr_chirps_20101231.tif" + 1)
The raster output will be dslr_chirps_20180101.tif
I have 10 years daily rainfall data and would like to calculate daily dry-spell for all the available data period.
How to loop the above calculation using model builder, when the output for each calculation will use as input for the next calculation?
