Aqua MODIS gridded ERDDAP chlorophyll

Dear ErthData team,

While exploring the ERDDAP database (https://coastwatch.noaa.gov/erddap/info/index.html?page=1&itemsPerPage=1000), I've noticed that Aqua MODIS data for chlorophyll is not listed. Interestingly, the same data is available through the Level 3 Browser Interface (https://oceancolor.gsfc.nasa.gov/l3/). Why is that discrepancy? Where is the Aqua MODIS data hidden in the ERDDAP database?

I want to download Level 3 Aqua MODIS data for a chlorophyll matchup analysis, where min_lat equals max_lat and min_lon equals max_lon (i.e., point location data). This specific requirement cannot be fulfilled using the Level 3 Browser, as it operates with max_lat greater than min_lat and max_lon greater than min_lon (i.e., polygon data). However, ERDDAP's access form allows me to achieve this. I'd appreciate any guidance on obtaining Level 3 Aqua MODIS data for my matchup analysis.

Thanks,

Anna

Hi Anna,

ERDDAP database is maintained by NOAA. You may want to try Earthdata Search (https://search.earthdata.nasa.gov/search).

Let me know if you came across any issues.
