Model simulation output, satellite data, and analysis codes for 2025 Santer et al. PNAS paper
Creators
Description
The model and observational datasets analyzed in the 2025 PNAS Santer et al. paper entitled "Human Influence on Climate Detectable in the Late 19th Century" are provided here. The codes used to produce the five main text figures are also provided, along with the "fingerprint" code.
Here is some brief information about the file naming conventions:
"sm6" - Denotes netCDF files with zonal-mean monthly-mean atmospheric temperature for six different atmospheric layers. These layers are:
- Stratospheric Sounding Unit channel 3 (SSU3)
- Stratospheric Sounding Unit channel 2 (SSU2)
- Stratospheric Sounding Unit channel 1 (SSU1)
- Microwave Sounding Unit/Advanced Microwave Sounding Unit temperature of the lower stratosphere (MSU/AMSU TLS)
- Microwave Sounding Unit/Advanced Microwave Sounding Unit temperature of the troposphere (MSU/AMSU TTT)
- Microwave Sounding Unit/Advanced Microwave Sounding Unit temperature of the lower troposphere (MSU/AMSU TLT)
"tf2" - Denotes TTT data. tf2 indicates that tropospheric temperatures have been adjusted for the effects of lower stratospheric cooling.
"RSS" - Denotes netCDF files containing observational MSU/AMSU TLS, TTT, or TLT data from Remote Sensing Systems in Santa Rosa, California.
"UAH" - Denotes netCDF files containing observational MSU/AMSU TLS, TTT, or TLT data from the University of Alabama at Huntsville.
"STR" - Denotes netCDF files containing observational MSU/AMSU TLS, TTT, or TLT data from the NOAA Center for Satellite Applications and Research (STAR).
"ss3" - Denotes SSU3 data from the STAR research group.
"ss2" - Denotes SSU2 data from the STAR research group.
"ss1" - Denotes SSU1 data from the STAR research group.
"piControl" - Denotes synthetic SSU and MSU/AMSU data from CMIP6 pre-industrial control runs.
"hst_ssp585" - Denotes synthetic SSU and MSU/AMSU data from CMIP6 extended historical simulations.
"r1", "r2", "r3", etc. - Identifies realization number for CMIP6 extended historical simulations.
"Fingerprint_Code1.F" - Fingerprint detection code.
"Main_Text_Figure_01.py" - Matplotlib Python code for plotting Figure 1 (there is a separate code for each of the five figures).
Further details of all model and observational temperature data sets are provided in the Materials and Methods and Supporting Information of the 2025 PNAS Santer et al. paper entitled "Human Influence on Climate Detectable in the Late 19th Century".
