Re: Spatial Subsetting Applications
Hi @ carlsopr Could you give to me some of the AppEEARS order IDs where you are seeing this. I am looking at your orders and I see 2 area and 5 point requests. Supposedly AppEEARS should process all available pixels with an actual value that falls within your search criteria whether it is over land ...

Re: MODIS cloud remove
Ideally, that would be the case, if you are asking me is it more necessary for that purpose then it is with others, I am not sure. But undoubtedly the more accurate Surface Reflectance value is with the lower Aerosol level. One of the inherent issues with daily data is to find the balance between se...

Re: Missing MCD43 data for tiles h19v01 and h18v01
Hi Silvia, First, we apologize for the version discrepancies. We did here back from the LDOPE folks at MODAPS who develop the production algorithms and process the data. They felt that it was due to more stringent sun angle criteria that was used with for V061 processing. They also verified that thi...

Re: MCD19A1
Hello, Sorry for the delay. We wanted to get confirmation about this from the PI/Developer of the MAIAC product because Band 4, 11, and 12 fall with in the green wavelength. He did confirm what we suspected, it is Band 4 that is aligned with the MCD19A2 optical_depth_550. Please let us know if you h...

Re: MODIS cloud remove
Hi Zhou,
It is recommended to use the Cloud State, as that is more definitive. Also, It contains, cloud mask from MOD35 and cloud/snow/aerosol/fire/shadow etc as determined by the reflectance algorithm. Hence users are encouraged to use the state flag from the MOD09GA.
Thanks,
Brett

Re: Unable to download certain GEDI L1B granules
Hi Q, Please remove the spaces and the quotation marks and I think it will work, with one condition. I discovered that Earthdata will only allow 5 granules at a time to be searched this way. When I put the entire list in it gave me this error: Error retrieving granules The query contained [26] condi...

Re: Download script for MODIS/Terra LST Daily 1km has different download URLS from collection granules shown
Hi, Can I point you in a little different direction. We have seen this issue with the Earthdata Search before when users try to subset. We are the LPDAAC, so the data comes from us, but the Earthdata Search is out of our control. Can you try our AppEEARS tool: https://appeears.earthdatacloud.nasa.go...

Re: MCD15A3H
Hi, LAI_Charts_China.PNG I processed February 1 through June 30 from 2012-2023 in our AppEEARS tool and they seem consistent, so at least there is no dramatic spike or drop from year to year, but the highest value I see is 2.3. The vast majority are between 0.5 and 1.5, so the issue is should they b...

Hello,
Could you send the search parameters you are using and also copy and paste the script? We would like to emulate exactly what what you are doing.

Re: MCD15A3H
Hello,
Could you give me some specific examples. Like the H/V Lat/long range and date, then we could look at specific examples. Also, did you get a chance to look at the QC bits to see if those would indicate what may be wrong with the pixels?
Thanks,
Brett
