Spatial Format : Timeseries for one site location

Notes          : This file contains flux tower data and MERRA-2 meteorological drivers for the CARDAMOM 
	       	 ecoystem carbon data assimilation scheme for the Bonanaza Creek Bog flux tower location
		 (PI: Eugenie Eurskirchen). The MERRA-2 data were regridded from their native resolution 
		 (0.625 deg x 0.5 deg) to the EASEv2 global 9-km grid to correspond with typical 
		 SMAP L4C processing. The precipitation and daily maximum 2m air temperature were pulled 
		 from GES DISC for this activity, all other fields were on-hand from previous SMAP L4C 
		 activities.  

		 The radiation field is downward incoming short wave which it what we use in L4C.

		 The precipitation field is the land-only bias-corrected precipitation provided in MERRA-2, 
		 which is also the precip forcing for the SMAP Nature Run soil moisture.

Known problems : GPP and RECO can be negative in the original reported fluxes. I set these non-physical 
      	       	 values to zero, therefore RECO minus GPP in this dataset is not necessarily equal to NEE.
