opendap MODISA missing data

Ahoy,

I have encountered a gap in the opendap service for

https://oceandata.sci.gsfc.nasa.gov:443/opendap/MODISA/L3SMI/2018/201/A2018201.L3m_DAY_SST_sst_4km.nc

The same data is available from the L3SMI browser and from direct data access.

Cheers,
Ben

Ben,

In a past life, we only pushed refined data to the OPeNDAP server.  When we changed the definition of refined, we relaxed that and allowed quicklook products to be distributed via OPeNDAP.
...except we didn't change the SST stream.  We will do so soon.

Regards,
Sean

Ahoy!

Ah.  I didn't know about the relaxation (it just proves that ignorance is bliss!)

We are using OBPG data for making 'now' casts - like this https://eco.bigelow.org/jellycast/ We do a daily download for a number of MOSDISA products.  Is OPeNDAP the right choice?  Of course we love being able to download only the subset we need on the fly, but we can chose a different method if that would be smarter.  Any wisdom to share on that?

Cheers and thanks,
Ben

Ben,

Well, funny you should ask...we are in the final stages of preparing a release of an updated L3 browser that will allow ordering extracted L3 data.
While that doesn't help you now, it sets the pieces in place to implement a L3 extract subscription service...something I've been mulling around for a while.  That would be exactly what you need.

For now, OPeNDAP should work (once we get the QL SST products flowing there) or you could gin up a daily query to our file_search API ala:

wget -q -O - "https://oceandata.sci.gsfc.nasa.gov/api/file_search?sensor=aqua&sdate=2018-08-01&dtype=L3m&search=A*_SST_sst_4km.nc&format=txt&addurl=1"

(just increment the sdate as appropriate)

Sean
