MSLP (Mean Sea Level Pressure) field of the Antarctic Mesoscale Prediction System (AMPS) dataset

Data are the MSLP (Mean Sea Level Pressure) field of the Antarctic Mesoscale Prediction System (AMPS) ( http://www2.mmm.ucar.edu/rt/amps/) available to download via www.earthsystemgrid.org. Data are 45km resolution for the domain d001 (lower left lat/lon = -24.72209 N, 38.30463 E, upper right lat/lon = -21.82868 N, -144.07805 E). Data are 3-hourly forecasts (t=0 to t=120) made every 12 hours using the Polar Weather Research and Forecasting (WRF) model. Data has been converted from grib to nc, 45km resolution polar stereographic to a 0.5 degree resolution latlon grid and concatenated into a single continuous dataset using the first 4 forecasts from each 12-hours. Where data was missing forecasts from the previous 12-hours are used.


Data available: 28/10/2008 to 31/12/2012.


Data were processed in this manner to be usable by the Melbourne University cyclone tracking scheme (Murray, R. J., and I. Simmonds (1991) A numerical scheme for tracking cyclone centres from digital data. Part I: Development and operation of the scheme, Australian Meteorological Magazine, 39, 155-166.) to investigate Antarctic polar lows.


Data are 3-hourly forecasts (from t=0 to t=120) made every 12 hours, which have been processed into a continuous 3-hourly dataset using the first 4 forecasts of every 12 hours. Missing data are filled by previous forecasts.

A copy of the data are available for download from the provided URL. Furthermore, the data are freely available to download via www.earthsystemgrid.org. Data were downloaded by Katherine Sadler (Polar research assistant, The School of Earth Sciences, The University of Melbourne, Parkville, VIC 3010) and requested from UCAR by Katherine Sadler and data were mailed on a hard drive. The website for the data is here: http://www2.mmm.ucar.edu/rt/amps/ The efforts to produce the data were sponsored by the National Science Foundation (NSF) Office of Polar Programs and the NSF UCAR and Lower Atmospheric Facilities Oversight Section. It is a collaboration of the National Center for Atmospheric Research and the Byrd Polar Research Center of The Ohio State University. Data were then processed by Katherine Sadler to get them into a usable form i.e. converted from grib to nc, polar stereographic to latlon and file reduced to MSLP field only to reduce the huge file size.

Statement
The only problem encountered was that downloading the data was very time consuming. You cannot download individual variables, so must download all variables making the data files very large which hence take a very long time to download (around 14 hours per month). Storage was also an issue, there is limited space available at the University of Melbourne, as such multiple months could not be downloaded and processed at the same time. Data files are still very large, but the data quality is good.
