could not find any data for variable "geoid_xgm2016" #147

Closed j08lue closed 5 years ago

j08lue commented 5 years ago

For a data extraction with CryoSat-2, we would like to use the improved geoid geoid_xgm2016 and can see it is defined in the rads.xml (as per #119). But when we request it from a recently synced RADS database, we get the message 

could not find any data for variable "geoid_xgm2016"

Is this expected or are we missing something?

Dear @j08lue . I'm afraid this is expected, as this geoid was only added to the processing since March 2018. So all data created after that should have it.

Meanwhile, I'll go and add this geoid at least to the CryoSat-2 data to help you out.

I can confirm that the c2 data from cycle 103 onwards already contains geoid_xgm2016.

geoid_xgm2016 has now been added to CS2 cycles 4-102, thus covering all of the mission.

Excellent, thanks. I can see it is just another variable in the source netCDF files.

I would actually like to use that geoid for many other missions. Is there any chance you could add it to the others, too?

I also propose an alternative to adding the geoid to all time steps: #148
