Dear Zhibo Zhang: In order to perform subsetting (both spatial and parameter subsetting) you can use LAADS post processing utility. This is available during the last step (5 REVIEW & ORDER) of search and order process. So, once you select the file(s) go to '5 REVIEW & ORDER' and click on App...

Files were temporarily unavailable because all systems were going through scheduled maintenance during last three days. Please, try now files are available again.

There are couple of ways you can reproject MODIS L1B swath products. You can utilize LAADS DAAC's post-processing option available from LAADS search and order interface. You can learn more about this option by reviewing tutorials provided at: https://ladsweb.modaps.eosdis.nasa.gov/learn/how-to-searc...

The LAADS post-processing during data order is probably the best option you have available. You can reproject your mosiac to Geographic grid using the "Reproject" option. You can find bounding coordinate in each files header metadata.

Production is on hold due to a satellite maneuver. The data testing and evaluation is in progress today and production should pick back up sometimes this afternoon or tomorrow morning.

All VNP46A1 data are available up to 2022-165 (June 14, 2022). How you are searching the data?

Data processing for L1 and higher level products is behind due to a delay in VIIRS L0 data from EDOS, L0 data provider.

Dear Peppe:
Thanks very much for sending the details. We investigate and will get back to you ASAP.
