Question: Cannot access ECCOv4 data from PODAAC via OPeNDAP

Re: Cannot access ECCOv4 data from PODAAC via OPeNDAP

For example, here is how podaac-data-downloader could be used for subsetting in a specific region:

% podaac-data-downloader -c ECCO_L4_TEMP_SALINITY_05DEG_DAILY_V4R4 -d ./ecco_data --start-date 2000-08-02T00:00:00Z --end-date 2000-08-05T00:00:00Z -b="-140,0,-110,33" --subset

Regards
Ed

Re: Cannot access ECCOv4 data from PODAAC via OPeNDAP

Hi Mike, That URL now resolves to the OPeNDAP form so I assume your issues are fixed. Sorry for not responding in a timely manner, but another suggestion is to use the podaac-data-downloader to do the subsetting on the ECCOv4 data. It is a python based tool that uses OPeNDAP on the backend to do net...

Re: MUR-L4 SST: Persistent Striping Artifacts near the Brazil Current

@miawang do you have the exact dates for the MODIS L3 SST and MUR SST images you posted ?

Re: MUR-L4 SST: Persistent Striping Artifacts near the Brazil Current

Hello Thanks for the info on the issues with MUR. I'm the lead POC for this dataset and help maintain the production system and software. I do agree that there is striping in many of the MUR images I have reviewed both recent and in the Sep 2010 time period from the original poster. But it appears t...

Re: MODIS Average quality level

Hi Sean,

Are those cloud screening tests are latitudinally based ? That is not the case here where a clear rectangle "box" is seen.

For the SST algorithm itself there are dependencies on latitudinal based coefficients but that is not what these plots are showing.

regards,
Ed

Re: MODIS Average quality level

Hi, I did discuss this artifact with an MODIS algorithm developer and scientist. Would you have the bandwidth to take deeper dive into problem? Several things could be done over the study region that shows a boundary problem: 1. Confirm the problem does not exist in either the Daytime or Nighttime M...

Re: MODIS Average quality level

Thanks, I did see the issue in the figure in the original post, so that is noted but its clearer in the zoomed figure of your response. I believe this is an issue with the cloud masking decision tree, but I will try to confirm with the MODIS SST algorithm developers at the Univ of Miami. Give me a f...
