Figure subpanels

---------------------------------------------------

There are technically two panels top and bottom (CMIP5 and CMIP6), however, the data is stored in the parent directory.

---------------------------------------------------

List of data provided

---------------------------------------------------

The data is for the Northern Hemisphere snow cover extent anomalies (SCEA) from models and observations:

- The SCEA observational data from GLDAS-NOAH (1948-2012), Brown-NOAA (1923-2017), Mudryk et al 2020 (1968-2017)

- The SCEA modelled by CMIP5 historical-rcp45 experiment (1923-2017)

- The SCEA modelled by CMIP5 historicalNat experiment (1923-2012)

- The SCEA modelled by CMIP6 historical-ssp245 experiment (1923-2017)

- The SCEA modelled by CMIP6 hist-nat experiment (1923-2017)

- The SCEA modelled by CMIP5 and CMIP6 piControl experiments

Data provided in relation to figure

---------------------------------------------------

snow_cover_extent_cmip5_obs.csv is the data for the green and brown lines and shadings in the upper panel and grey lines (1923-2017)

snow_cover_extent_cmip6_obs.csv is the data for the green and brown lines and shadings in the lower panel and grey lines (1923-2017)

snow_cover_extent_piControl.csv for the blue error bars in the both panels
