Please see the manual for the description of the data and the use of the visualization tool. 

 

Dataformat

Each datafile contains different fields that are explained in the header and that we remind here: 

TIME: Time value in number of days since 1st January 1980

WAVELENGTH: Wavelength in nm.

DATA: Irradiance in W/m^2/nm (W/m^2 for broad-band instrument)

INSTRUMENT_ACCURACY: Irradiance accuracy as determined from the instrument team. 0 if not present (means refer to original publication or data release)

INSTRUMENT_STABILITY: Irradiance stability (long-term repeatability, uncertainty on the instrumental trend) as determined from the instrument team. 0 if not present

INSTRUMENT_PRECISION: Irradiance precision (short-term repeatability or stability) as determined from the instrument team. 0 if not present

SOLID_FLAG: Flag value between 0 and 31 indicating if the observed original irradiance has been modified or not:0: Original data untouched.1: Original data were missing or obvious outlier greater than 16 sigmas2: Several irradiance values for one date4: Data have been regridded in time to be centered around noon.8: Data have been detected as outliers using an auto regressive models16: Data points ave been replaced with a local proxy fitting model (done for data points already having flag value between 1 and 8). For ex., one missing data point that has been replaced with a local proxy fitting model will have value 16+1=17

SOLID_PRECISION: Irradiance precision (short-term repeatability or stability) in W/m^2/nm) as determined within SOLID. See Scholl et al., 2016

SOLID_STABILITY: Irradiance stability (long-term repeatability, uncertainty on the instrumental trend) in %/year as determined within SOLID.   

More details are given in Schöll et al. (2016) and Haberreiter et al. (2017).
