I am working on a project estimating biomass production and carbon storage in mangrove forests.
I looked upon examples estimating biomass production using NPP and GPP such as https://mygeoblog.com/2016/10/19/biomass-production-from-npp/ and https://mygeoblog.com/2016/10/18/measuring-carbon-storage-from-space/ .
These examples are using Modis MOD17A3H.006: Net Primary Production Yearly L4 Global 500 m and MYD17A2H.006: Gross Primary Productivity 8-Day L4 Global 500 m data.
But these products are lacking data in mangroves sites (I am focussing on Sundarbans and some other mangrove sites in India). Of which I think the reason is that wetlands are assigned fill values https://lpdaac.usgs.gov/dataset_discovery/modis/modis_products_table/mod17a2h_v006 and https://lpdaac.usgs.gov/dataset_discovery/modis/modis_products_table/mod17a3h_v006 .
Can anyone guide me what dataset would be best for mangroves? Can you guide with examples and algorithm to use?
