PMIP4 SATIRE-M solar forcing data

The files contain Solar Spectral Irradiance reconstruction based on 14C or 10Be and the SATIRE-M model, with and without an adaptation of the spectral irradiance to the CMIP6 historical forcing.

14C data for the last 9000 years (6754.5 BC to December 2015)

10Be data for the years 885 CE to December 2015

The data set scaled to the CMIP6 historical forcing is the recommended forcing for the PMIP4-CMIP6 tier-1 past1000 experiment.

scaling =

fc: adaptation of the spectral irradiance to the CMIP6 historical forcing

nfc: no re-scaling

Data format

The data are provided in simple text format. The file structure is as follows:

1st array: wavelength array in [nm], listing the center of each wavelength bin.

2nd array: wavelength bin in [nm], listing the bin width of each wavelength bin.

3rd array: time in [year] (floating numbers).

4th array: SSI reconstruction in [W m-2 nm-1]. SSI is average SSI in corresponding bin.

We provide the following IDL code to read the .txt file and calculate TSI:
