Re: Missing Production CLDPROP NPP/VIIRS Software?
Dear Nick: Specifying product makes a big difference. The MODAPS page you were referred was for software that are used to generate products at MODAPS-LAADS (MODIS level 1, atmosphere,land, and VIIRS level1, land, and other products) . However, NASA's Atmosphere Science Investigator-led Processing Sy...

Re: The convention of the sensor azimuth and the solar azimuth variable provided in the MYD06 data product
The solar azimuth angle is the compass direction from which the sunlight is coming at a particular location and time. The sensor azimuth angle is the direction from which the satellite sensor is viewing the target point on the Earth’s surface. The angle 0 degree represents north, 90 degree represent...

Re: v002 delays and incomplete updates VJ113A1 VNP13A1
We checked and for the VNP13A1 and VJ113A1 for June 17, 2024 the tiles you asked about are all available. Full suite of products were generated on July 3, 2024. The VI (VNP13A1/VJ113A1) is a 16-day product, so the outputs are not created until 16-days (give or take a little) from the start time of t...

Re: MOD06_L2 data ranges and missing data
Our product SME investigated MOD06_L2 data and found how to distinguish Cloud_Optical_Thickness (COT) between no data case and failed retrieval. For example, for 2.1 micron (band 7), the valid range for scaled Cloud_Optical_Thickness (1354, 2030) is [0,150]. The valid range for scaled Retrieval_Fail...
