Re: Missing data in MODIS/Terra+Aqua AOD and Water Vapor from MAIAC, Daily L3 Global 0.05Deg CMG V061
Hello, Could you give us more specifics on the area that is missing data. If it is over deep ocean, that is expected. Please see page 6 of the User Guide for more information on this: https://lpdaac.usgs.gov/documents/1500/MCD19_User_Guide_V61.pdf If it is over land can you give us a coordinate rang...

Re: Help Looking for and Downloading Climate Change Variables for Research on Agricultural Productivity in Peru
Hi Brayan, I see there are about 8,712 files to download, I wonder if the browser is limiting the download size? Can you try a different option, wget seems to work well: https://github.com/nasa/LPDAAC-Data-Resources/blob/main/guides/bulk_download_using_wget.md Possibly a different browser might work...

Re: Help Looking for and Downloading Climate Change Variables for Research on Agricultural Productivity in Peru
Hi Brayan, Another option that may help is the LPDAAC AppEEARS tool: https://appeears.earthdatacloud.nasa.gov/ It has many of our products available through it including the MOD/MYD21 products: https://lpdaac.usgs.gov/product_search/?query=mod21&status=Operational&view=cards&sort=title A...

Re: APPEEARS API - Available images endpoint?
Hi Juliano,
AppEEARS is probably not the best option for this. It is designed to process the data so it will not have a very quick turnaround time. We do suggest NASA Earth Access however: https://earthaccess.readthedocs.io/en/latest/
Please let us know if you have any questions.
Thanks,
Brett

Re: MOD13Q1 NDVI data preprocessing
Please note the .csv file AppEEARS outputs does incorporate the scaling factor. However, the pixel values in the output raster images are not scaled. So yes, the csv values are scaled.

Re: MOD11A2 Terra vs Aqua shift
Hello,
Can you give me more specifics about the offset. How many meters do you figure it is, I am not seeing it in the archived tiles, but I may not be looking in the right place.
Thanks,
Brett

The Science team decided to reprocess the data from January 1 through May of 2022. The duplicate removal script was having some issues also. So, there are some duplicate...

I would like to suggest to you our AppEEARS tool: https://appeears.earthdatacloud.nasa.gov HLS is available in AppEEARS and it does all this automatically. You can make an area sample request and it mosaics and does all...
Re: MCDLCHKM.
Hi Jonas, I don't believe that this product has ever been archived and distributed, it is used only as an upstream product used to produce other MODIS products. You may want to check with MODAPS to confirm this as they are the data providers: https://modaps.modaps.eosdis.nasa.gov/services/user/ Than...
