Question: MERIS TSM western US coast

Re: MERIS TSM western US coast

We cannot provide support for the ESA data distribution site, for that I suggest contacting the ESA services desk . The L2 data distributed by the Ocean Color Web interface does not include a TSM product as it is not the ESA product, but rather an Ocean Biology Processing Group (OBPG) produced produ...

Re: Depth of data provided

SST is a skin temperature, not a bulk temperature. The products derived from the optical measurements (i.e. Rrs) do not have a defined depth. They are "surface" values, though the definition of surface is not set either, but is assumed to be equivalent to the first optical depth which vari...

Re: When I use the l2gen module to process and generate MODIS rhos products, the process is very slow.

There are numerous reasons why processing may be slower than expected, most of which are related to I/O. One thing you can do is to run with atmocor=0, this will disable a lot of unnecessary processing that setting aer_opt=-99 doesn't do. Although it does disable aerosol selection and removal, it do...

Re: Day/Night filter with wget

Jane, Unfortunately, no, the file_search API does not support selection of data base on the day/night flag. However, the CMR API *does* provide this information. Here is an example query: curl "https://cmr.earthdata.nasa.gov/search/granules.csv?page_size=10&sort_key=short_name&short_nam...

Re: cite

I'll assume by the L3 browser you refer to: https://oceandata.sci.gsfc.nasa.gov/l3/ The data access tool is not really relevant, as the various tools all return from the same source, which in this case is the OB.DAAC. Examples of how to cite data retrieved from our archive can be found here: https:/...
