AMPS consists of several domains ranging in horizontal resolution from 90 km covering a large part of the Southern Hemisphere, to 3.3 km over the complex terrain surrounding McMurdo Station. Several published studies have shown the model performs with good skill on hourly to seasonal timescales. On seasonal timescales the intraseasonal and interseasonal variability in pressure, temperature, wind, and moisture are well-resolved.
In addition to the real-time applications of AMPS, a continually evolving database of archived forecasts yields high-resolution climatological data that are useful to a broader Antarctic research community. For example, temperatures, 3-dimensional winds, and several moisture proxies are available for about 30 levels in the atmosphere from twice-daily forecasts at 3-hourly temporal resolution on a 30-km grid covering the entire continent. Precipitation, cloud fraction, and complete energy flux fields are also available. These forecasts can be integrated to compute time-mean fields on monthly, seasonal, and annual timescales. Soon the AMPS archive will be available to the Antarctic research community via an Internet database.
