Question: LAADS DAAC API-V2 VIIRS Data Product Latency

Re: LAADS DAAC API-V2 VIIRS Data Product Latency

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.

Re: Missing CMR API Data Dec 1st/2023 (A2023335)

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...

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: 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...

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.
