Can we add more supported MODIS products #169

Closed HuaiweiSun closed 5 years ago

HuaiweiSun commented 5 years ago

We found some cloud cover products are very useful. Can we add more supported MODIS products (such as MYD08_M3, etc) in this package?

If we would like to add the MODIS products by ourself, how can we modify this package?

@HuaiweiSun

Adding "new products" is possible, but only for products generated with the "standard format" of MODIS land products. Could you point me to some reference describing the MYD08_M3 product, and to the http archive for its download?

HuaiweiSun commented 5 years ago

I found the descriptation of MYD08_M3 can be found in https://ladsweb.modaps.eosdis.nasa.gov/missions-and-measurements/products/l3-atmosphere/MYD08_M3/. Also, there is a daily level 2 product (MOD06_L2) in https://modaps.modaps.eosdis.nasa.gov/services/about/products/c6/MOD06_L2.html.

@HuaiweiSun

I had a look: MOD08 is a "Atmosphere" product, distribited by LAADS DAAC. Unfortunately, I can not easily support that product because it is not part of the products distributed by LP DAAC , and therefore has a completely different structure, naming convention etcetera. Product that can be supported by MODIStsp, or for which support can be easily implemented, are those reported here:

https://lpdaac.usgs.gov/product_search/?collections=Combined+MODIS&collections=Terra+MODIS&collections=Aqua+MODIS&view=list

I do not know if/when I'll be able to add support for products distributed by other DAACs, sorry.
