We were having some issues with our data download system since Monday afternoon which have been fixed so you should be able to download data now. Please, try again and let us know if you still cannot download.

Dear Marco Laiolo: Currently, we are working on generating geoMeta for NOAA-21 (JPSS-2). We are hoping to have this available sometimes towards the end of February or early March. Please, check back around that time. These will be available at: https://nrt3.modaps.eosdis.nasa.gov/archive/geoMetaVIIR...

No, MODIS Collection 5 (C5) data are already decommissioned and deleted from the archive, so cannot be downloaded. The latest version is C61 which you should be using:

Try python code examples provided by HDF-EOS Tools and information center at: https://hdfeos.org/zoo/index_openLAADS_Examples.php#MODIS If you still have question or need further assistance, contact their support at: https://hdfeos.org/help/index.php or by sending e-mail directly to eoshelp@hdfgroup...

The latency information provided in the table on the EarthData webpage are accurate. So, latency varies with type and level of a product, but generally between few hours to few days and in some cases (for higher level products) even a month or more.

Dear Shane: Sorry for the delay in response. The example you listed is not valid since NRT data files from Dec. last year don't anymore. However, data files from current period do exist: https://search.earthdata.nasa.gov/search/granules?p=C2007661943-LANCEMODIS&pg[0][v]=f&pg[0][id]=*A2024006...

No, it will select all granules that intersect with the defined bounding box. So, search will find all granules listed in your examples and will not ignore any.

You can repeat your coordinates with a minor difference (e.g., 74.32,31.54,74.33,31.55).

Dear Marco Laiolo:
We don't have a final date for the release of VIIRS/JPSS2 data right now. We will post the announcement on LAADS website once the data are ready for release. The information will be posted at:

In MODIS L3 COSP, the cloud fractions are aggregated at different pressure levels, there is no layer overlap: Cloud_Mask_Fraction: (all pressure levels: total column) Cloud_Mask_Fraction_Low: (CTP >= 680 hpa) Cloud_Mask_Fraction_Mid: (440 hpa <= CTP < 680 hpa) Cloud_Mask_Fraction_High: (CTP < 440 hp...
