I'm looking at a time series of NDVI values for the state of New York using weekly MODIS NDVI values. I'd like to either mask out clouds, or exclude weeks with a specific cloud cover percentage (like 20% cloud coverage over New York). Is there a way to do this without just eyeballing the values?
Hi Hollis,
I think it can be done easily in Google Earth Engine. Have a look at the following link where they used cloud mask function to remove the clouds:
https://developers.google.com/earth-engine/ic_composite_mosaic
Also, a very recent publication used the similar thing for NDVi estimates
Article The Grass Is Not Always Greener on the Other Side: Seasonal ...
Cheers
on removal of clouds, you may wish to consider the approach in the section 2.2 of
Article A novel approach to optimize hierarchical vegetation mapping...
This can be achieved through cloud computing usually with Java and Python scripting in GEE.
It is possible to enhance image collections with more than 20% cloud cover.
Thank you.
