Amplification Function of Maximum Likelihood Estimates of Temperatures using Data from the Hadley Centre and the Climate Research Unit (Version 1.2)

Calvert, Bruce

Dataset
Summary
This dataset consists of the estimated amplification function of HadCRU_MLE_v1.2. The amplification function varies by 5° latitudinal band, surface type (open sea vs land/ice), and calendar month. The amplification function is intended to reflect the observed tendency of different regions to warm faster or slower relative to the global average. However, observed local amplification factors (i.e., how fast a location on the planet warms relative to the global average) may differ substantially from the estimated amplification functions. Results of sensitivity tests using alternate sea ice source datasets from the Japanese Meteorological Agency (COBE-SST2) and the National Snow and Ice Data Center (modified G10010v2 appended with G02202v4) are also available.

Description
The quality of this dataset has been approved by Bruce T. T. Calvert on February 19, 2024. This dataset is a further derived product (classifying as a level 4 data processing level) derived from various source datasets, including land surface air temperature anomalies of HadCRUT5, sea surface temperature anomalies of HadSST4, sea ice coverage of HadISST2, land mask data of OSTIAv2, the surface temperature climatology of Jones et al. (1999), the sea surface temperature climatology of HadSST3, surface elevation data of GMTED2010, and climate model output of CCSM4 for a pre-industrial control simulation. Sensitivity tests of HadCRU_MLE_v1.2 use alternate sea ice source datasets (COBE-SST2, G10010v2, and G02202v4). These source datasets either have had extensive quality control or are themselves further derived products based on source datasets that have had extensive quality control.
Description
There are no missing values for the estimated amplification function. The estimated amplification function is spatially complete for all 5° latitudinal bands.
