Re: Error in Product "MODIS/Terra Vegetation Indices Monthly L3 Global 1 km SIN Grid" for March and August 2024

Hi Brett,
thank you so much for this quick fix! I plotted all monthly layers from 2000-2025 and these 2 were the only ones with errors.
Thank you so much again.
Best,
Anne

Hi Brett,
thank you so much for the explanation of how the monthly layer is calculated. That is very helpful. I will wait some days, and if the data takes longer to be available that I just calculated myself.
Thanks!

Re: Error in Product "MODIS/Terra Vegetation Indices Monthly L3 Global 1 km SIN Grid" for March and August 2024

I guess fixing this will take some time. How exactly are the monthly data averaged?. In the documentation it says "In generating this monthly product, the algorithm ingests all the MOD13A2 products that overlap the month and employs a weighted temporal average." Is this algorithm available...

I have recently downloaded all monthly tiles over all available years (2000-present) of the product "MODIS/Terra Vegetation Indices Monthly L3 Global 1 km SIN Grid". All rasters are complete, besides March and August 2024 (see plots attached). In these two many tiles are missing. I checked...
