Re: Missing MODIS v6.1 data on Dec 22 2023

Hi Katya, Sorry for the delay. They are not recoverable, unfortunately this will occur more often as the Terra and Aqua platforms orbit decays. Please see the following also: Data gaps or missing data have become more of a routine occurrence for Terra, Aqua, and Terra+Aqua Combined MODIS data produc...

Question: MODIS band 6, or LSWI, at 250m resolution?

Re: MODIS band 6, or LSWI, at 250m resolution?

Hi Tim,
Unfortunately I am not aware of any entity that has resampled the 500 meter data to 250. MODIS Bands 1 and 2 are the only 250 meter bands and bands 3-7 are 500 and 8-36 are 1000 meters. WIsh I could be of more help.
Thanks,
Brett

Re: Problems downloading VNP15A2H v002 vegetation products

Hi Enrique, Yes, that is a good idea and that is in the works. Right now the data base administrators are accessing what is all missing. It varies with each product. The data providers are not giving us any timeline, as I don't think they have any idea at this point. Thanks for your patience. Brett

Hello, Yes, the VNP14A1 V002 has been released. Unlike V001 it is not available in the Data Pool, but rather it is in the cloud. It can be searched for and ordered through the Earthdata Search Tool: https://search.earthdata.nasa.gov/search/granules?p=C2545314541-LPCLOUD&pg[0][v]=f&pg[0][gsk]...

Re: Problems downloading VNP15A2H v002 vegetation products

Hi Enrique,
Sorry for the delay with the V002 processing. The data providers have been made aware of this and we are trying to reconcile the discrepancies and fill in the gaps. Unfortunately, we do not have a firm timeline on when this will be complete. Thanks for your patience.

Re: MCD19A2 AOD data preprocessing

Hi afnanullah279 Looked into this a bit: Optical_Depth_055 refers to Green band aerosol optical depth, according to the user guide the description for AOD uncertainty states: AOD uncertainty: This parameter is evaluated based on the Blue-band B3 surface brightness (reflectance) only, and thus gives ...

Re: Missing MOD11A2.061 tiles from 2001

Hi Mauricio, We will pass that along about the missing data from the cloud as compared to the Data Pool, thanks for the heads-up. On the matter of 2001 June 18, unfortunately that composite never was. To date the longest downtime that any MODIS sensor had was June 17, 2001 until July 4, 2001. The sa...

Re: MOD16A2 Unit Conversion

Hello, We typically work in metric but I'll see if anyone on our staff knows an easy way to convert. In the meantime, if anyone in the science community works in imperial we'll leave it open for you to share what you do. It does appear that the .csv file allows formulas to be entered for specific co...
