The Value of Multi-proxy Reconstruction of Past Climate
Data:
- North hemisphere temperature data from climate model: data
- Volcanism: data
- Solar: data
- CO2: data
- 15 temperature series to generate synthetic tree rings – data
- 10 composite temperature series to generate synthetic pollen – data
- 5 composite temperature series to generate synthetic borehole profile – data
- R code for 40 reconstructions correponding to Figure 5
Five models:
- (T) Reconstruction using “oracle” proxy
- (D) Reconstruction using tree-ring
- (DP) Reconstruction using tree-ring and pollen
- (DB) Reconstruction using tree-ring and borehole
- (DBP) Reconstruction using tree-ring, pollen and borehole
R files for each of five models under 2^3 factorial designs:
(For each scenario, there is a Common R file that reads the data and define functions and is shared by five R files for each model)
- With forcings, without proxy noise, modeling T: Common, (T), (D), (DP), (DB), (DBP)
- Without forcings, without proxy noise, modeling T: Common, (T), (D), (DP), (DB), (DBP)
- With forcings, without proxy noise, modeling T1: Common, (T), (D), (DP), (DB), (DBP)
- Without forcings, without proxy noise, modeling T1: Common, (T), (D), (DP), (DB), (DBP)
- With forcings, with proxy noise, modeling T: Common, (T), (D), (DP), (DB), (DBP)
- Without forcings, with proxy noise, modeling T: Common, (T), (D), (DP), (DB), (DBP)
- With forcings, with proxy noise, modeling T1: Common, (T), (D), (DP), (DB), (DBP)
- Without forcings, with proxy noise, modeling T1: Common, (T), (D), (DP), (DB),(DBP)
