| Description: | DATA REPROCESSED and CORRECTED:
To produce a continuous estimate of clear-sky shortwave irradiance in climates that
infrequently have clear-sky conditions a single set of clear-sky coefficients are calculated
for the entire run rather than a series of daily coefficients. GRW is such a site, but it
was not processed using this technique originally. The impact affects variables that use
these coefficients in their calculations.
The Radflux1long .c2 level datastream was reprocessed to generate the correct coefficients
in March 2017. Please retrieve the reprocessed data for use in your analysis.

---------------------------------------------------
To produce a continuous estimate of clear-sky shortwave irradiance in climates that
infrequently have clear-sky conditions a single set of clear-sky coefficients are calculated
for the entire run rather than a series of daily coefficients. GRW is such a site, but it
was not processed using this technique. The impact is to all primary measurement values
as they are calculated using the coefficients calculated by the fit method used. |
