Snow Covered Area & Water Resources - Kajaki Dam Catchment, Afghanistan

The Snow Covered Area (SCA) can be used to predict upcoming floods & droughts during the irrigation season in Central Asia. In this video I will show you how to download and process SCA data from Afghanistan to predict the floods of 2019 and 2020 and the droughts of 2018 and 2021. We will be using the 500x500 metre resolution MODIS MOD10A2.006 dataset. It will be processed in AppEEARS to give us the number of pixels classified as snow, land, water and cloud cover for the Kajaki Dam catchment in Helmand Province from 2000 to present.

We will import this dataset into a Table in an MS Excel Template, where we will process it automatically using customised formulas and PivotTables. The output will be presented in a PivotChart controlled by a Slicer so you can look at individual years of data from 2021 to present.

My special thanks to Naseer Kajakiwal for sharing with me some recent pictures of the terrible drought situation in Helmand Province.
