On Earthdata Search, when you find a data collection of interest, such as NOAA-20 VIIRS SST , click the three dots in the top-right corner and select "Collection Details" to find information about the collection. For more details, click "View More Info". For example, the NOAA-20 ...

Hello,

Sorry, CDO is not our software, so I can't provide a solid answer to your question. If you are using our L3M data, I recommend using our software SeaDAS (https://seadas.gsfc.nasa.gov) for regridding/remapping purposes.

Best,

Yes, you can automate the download of NOAA20/21 VIIRS SST data using the Earthdata Python package earthaccess. The URL you referenced points to direct data access, but earthaccess can streamline the process by querying and downloading data directly from Earthdata's API. Here’s a general approach you...

Hello, Thank you for reaching out with your questions regarding the challenges of detecting harmful algal blooms (HABs) in persistently cloudy regions. Here are some potential approaches to consider: 1. Increasing Coverage Despite Cloud Cover Persistent cloud cover is a common challenge in satellite...

Hello, Unfortunately, it’s not possible to download historical versions of the imagery. All imagery is based on the most recent reprocessing and parameters, and older versions are not retained in the archives. We apologize for any inconvenience. If you’re interested in accessing the most recent vers...

Hi Thomas, Yes, the normalized water-leaving radiance is used in nFLH calculation rather than normalizing FLH. You may want to refer to the following ATBD and the corresponding reference for more details regarding the nFLH algorithm: https://oceancolor.gsfc.nasa.gov/resources/atbd/nflh/ Hope this he...

For case-1 water, where phytoplankton is the primary constituent influencing the optical properties, the algorithms for Chla, Kd490, and POC were developed based on this assumption. If we’re discussing similarities among NASA standard products for these variables, the algorithms’ shared foundation i...
