Re: API-V2 Details Endpoint Regions Parameter Usage
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.

Re: Downloading MODIS AOD data for a specific point
You can repeat your coordinates with a minor difference (e.g., 74.32,31.54,74.33,31.55).

Re: VIIRS-JPSS2 Data
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:

Re: How to select low level warm water cloud fraction in MODIS MCD06COSP dataset
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...

Re: LAADS request for GCMD Keywords
Tyler, We reviewed the keywords and both looks fine. However, one of the eMAS project member provided following feedback (for Instrument Keyword: eMAS ): "..., the “eMAS” keyword link text is indeed from the eMAS home webpage, but includes only the first paragraph of text from the “Overview” se...

Re: How to select low level warm water cloud fraction in MODIS MCD06COSP dataset
Yes, this is a correct way.
The logic is to find the pixels with valid cloud fraction values for both Cloud_Mask_Fraction_Low and Cloud_Retrieval_Fraction_Liquid, then for these pixels you can use either Cloud_Retrieval_Fraction_Liquid or Cloud_Mask_Fraction_Low.

Re: How to select low level warm water cloud fraction in MODIS MCD06COSP dataset
Below is a response from our SME: Cloud Mask Fraction Low: it is based on cloud top pressure (CTP >= 680hpa) for daytime (SZA <= 85 deg). The daytime cutoff is less strict than cloud optical properties (SZA <= 81.3731 deg), so the data extends a bit farther poleward. It may include liquid, ice, or u...
