Re: Appeears - MOD11a2 - Scaling factor added to tif via tiftag?

Hi,
The output tiffs should be scaled for point data, but for area samples they are not scaled. Please let me know if you have any questions.
Thanks,
Brett

Re: VNP21A1D.001 data availability

Hi,
Unfortunately, that delay is to be expected. The atmospheric input data used to process the MOD/MYD21A1 data sets are created monthly after the end of the corresponding month so there will always be that delay.
Thanks,
Brett

Re: HLS v2.0 data availability

Hi Kim-Cedric, The HLS providers are just beginning to process the pre-2021 Sentinel data into the HLS data set. The Sentinel 2 data has been reprocessed and is now compatible with the HLS. The plan is to begin with the 2020 data and work back to 2015. It is scheduled to be complete this fall. Thank...

Re: MODIS aqua and terra L0 data paused stagging since yesterday (1/15/2023)

Good Morning,
Do you have a particular MODIS data set(s) you are interested in? I am looking in our Data Pool and I do not see missing data, at least of the products I checked.
Thanks,

Re: modes detected by Gaussian fits

Hi Maye, Sorry for the delay, we needed to get direction from the GEDI Science team on this, fowwlowing is their response: The two data layers that you have indicated, “num_detectedmodes” and “selected_mode”, are only part of the bigger picture here. The “num_detectedmodes” layer is simply a count o...

Re: update to HLS v2.0 processing schedule?

Hi, The latest that we hear is that back processing will resume in February and be complete by the end of the year. The Sentinel data was reprocessed so that access to the data will be much less problematic which will make the processing of the HLS Sentinel go much smoother. Thanks for your patience...

Re: MO(Y)D13A2

Good Morning, The MYD13A2.A2018361.H28v06.061.2022004082359 uses the last 4 days of 2018 and the first 12 days of 2019. So in fact there is some overlap where acquisitions from several days are used in 2 consecutive composite period. Day 9, 10, 11, and 12 of 2019 (and every year) are used to average...

Re: Is there an API for spatially subsetting and downloading GEDI data?

Hi,
The date is TBD, depending on the data availability. We will post when we have more information on the release of the next version of GEDI data. We will also have a better idea of when AppEEARS can be made compatible with the GEDI.
Thanks,

Re: MCD43 BRDF_Albedo_LandWaterType on 30 ArcSec grid

Hi It has been too long and we don’t exactly remember why we didn’t attempt to include a dynamic 30arc second land/water mask in the MCD43D (and VNP43D) CMG products – (other than attempting to save archive space, which was more of an issue a decade ago), but we have some vague idea that we thought ...
