Include observations in LDF

Open wwieder opened this issue 9 months ago • 2 comments

What is this new feature?

No observations are currently being used in the land diagnostics.

  • [ ] Populate datasets in central location (e.g. /glade/campaign/cgd/amp/amwg/ADF_obs),
    • Maybe this lives in a CUPiD observations home?
    • Alternatively we could just draw from ILAMB?
  • [ ] Regrid to standard resolution(s) (start with f09_t232)
  • [ ] Include any unit conversions, I think these go into lib/ldf_variable_defaults.yaml
  • [ ] Check that plots look as expected

The (very old) observations that the NCL-based diagnostics package uses are here:

/glade/campaign/cgd/tss/people/oleson/FROM_LMWG/diag/lnd_diag4.2/obs_data

2-m temperature and precipitation (Willmott and Matsuura, 2000) UNH-GRDC composite runoff fields (Fekete et al., 2000) USAF/ETAC snow depth (Foster and Davy, 1988) CMC snow height and total snow water equivalent (Brown et al., 2003) NOAA/AVHRR fractional snow cover (Robinson and Frei, 2000) MODIS albedo, VIS/NIR Direct/Diffuse (2001-2003, courtesy of P.Lawrence) Continental freshwater discharge (Dai and Trenberth, 2002) FLUXNET-MTE latent heat, gpp (Jung et al. 2010; Beer et al. 2010)

The observations that ILAMB uses are here:

/glade/campaign/cesm/community/lmwg/diag/ILAMB/DATA

Updated datasets can be downloaded periodically by running ilamb_fetch (see README in /glade/campaign/cesm/community/lmwg/diag/ILAMB).
