Additional satellite data
Vegetation indices (MODIS EVI) or Land Surface Temperature data (MODIS)
Change detection determines if rainfall occurred
Challenges
Relate magnitude of change (Vegetation or temperature) to rainfall amount and relevance for ground water recharge
Validation using change detection of land surface

Linking ground observations to satellite data
Land surface temperature observations – on test site
Measure land surface temperature signal before and after different sprinkler irrigation scenarios
Determine duration and magnitude of sprinkler irrigation related surface temperature signals
Determine relevant rainfall events required for ground water recharge

Does recharge occurs under sand cover and aridity?
Indications are given...
...however, investigations so far never below point of no return
