Question: MODIS Aqua SST data citation and documentation

Re: MODIS Aqua SST data citation and documentation

The OBPG is the processing center and while we do distribute the data, the PO.DAAC is the archive center. Here's a link to the PO.DAAC page on the MODIS-Aqua 9km product (which has a tab for citation :D ) https://podaac.jpl.nasa.gov/dataset/MODIS_AQUA_L3_SST_THERMAL_MONTHLY_9KM_DAYTIME_V2019.0 Regar...

Re: Subsetting MODIS-AQUA download by lat/lon with wget?

Anthony, We also support extracted subscriptions, but currently only or L1 and L2. It is our plan to extend that support to L3. Another plan in the works is to have the file search API support spatial searches (currently it only does temporal) and allow it to submit extraction requests. ...that migh...

Re: Subsetting MODIS-AQUA download by lat/lon with wget?

Anthony, That example is to an existing extracted L1A file (one used by our SeaBASS team for doing validation analyses). We do not support extracting on the fly, but do offer extraction via data orders for L1, L2 and L3 data. Using the L3 browser, you can request spatially extracted data to be stage...

Re: Error finding SeaHawk products

The file you listed (and likely the 13 others you found) were flagged for bad quality, but after the CMR record was generated. The ocean color L1/2 browser and our download tools knows about this flag and so stubbornly refuse to show the file. The CMR records have been scheduled to be removed (there...

Re: Question about using wget on for Aqua and Merra2

Whether or not I use the password credentials in the wget command, the result is a file with the .nc extension: Yes. The wget program has no idea what filetype is being sent, just that you requested some file (with a .nc extension) and some data was sent to you (so it saved it to a file with the na...

Re: Question about using wget on for Aqua and Merra2

To answer the question about needing (or not) to pass username/password to wget for the SST data download...you do need to do so. Did you look at the file you downloaded without the credentials? What I'm pretty certain you will find is that it is NOT a netCDF file, but rather an HTML file that is th...

Re: modis_GEO -- Percent valid data (46.00) is less than threshold (95.00)

It's not you, or the code. There is some bad orbit data from 1/31. If we get updated att/eph data that corrects the problem, the data will be reprocessed (you'd need to pull the updated files, but I do not know when or even if they will be available). If you look at https://oceandata.sci.gsfc.nasa.g...

Re: mapgen script with MODIS L2

The binner cannont bin the flags because they are a bitwise value that cannot be expressed as a floating point value. The binner uses the l2_flags to exclude data during the binning process - which is what the options you defined in the graph were doing for the band maths step. The flaguse parameter...

Re: Oceandata missing SEAICE_NSIDC_24h.hdf ancillaries for 2023, except DOY 001

The NSIDC-based SEAICE files have been deprecated and are no longer produced. We now use the sea ice fraction field in the CMC SST file to set the flag. The l2gen icefile option accepts this file.
