Description
JM Van Wessem from Utrecht University provides a data set of yearly regional atmospheric climate model (RACMO2.3p2) data over Antarctica. It includes historical data from 1950-2014 and future projections under three SSP scenarios from 2015-2100, as well as a reanalysis-forced product from 1979-2021. The data contains yearly averages for precipitation, snowfall, snowmelt, sublimation, and 2-meter temperature.
Use Cases
Projecting future Antarctic surface mass balance based on CMIP6 scenario data.
Analyzing historical trends in liquid water production and snow accumulation from 1950-2014.
Calculating melt-over-accumulation sensitivity as a function of annual average 2-meter temperature.
Studying the spatial distribution of climate variables across the Antarctic ice sheet using provided latitude, longitude, and elevation grids.
Strengths
Covers a long temporal range from 1950 to 2100, including future projections.
Includes data forced by multiple sources: ERA5 reanalysis and CESM2 historical/future scenarios.
Provides specific spatial coverage for the entire Antarctic ice sheet at 27 km horizontal resolution.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
Last update date is unknown; freshness unverified.
