This dataset includes five-minute reports with elements for wind speed and direction, visibility, present weather, temperature, dew point temperature, station altimeter, pressure and density altitude, and relative humidity for approximately 900 stations in the U.S., Puerto Rico, the U.S. Virgin Islands, and some Pacific island territories as part of the Automated Surface Observing Systems (ASOS) network. The ASOS Program is a joint effort of the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the Department of Defense (DOD). The ASOS network was designed to support weather forecast activities and aviation operations and, at the same time, support the needs of the meteorological, hydrological, and climatological research communities. The ASOS 5-minute data were collected and processed by the NOAA National Centers for Environmental Information (NCEI).

The STORM-FEST 5-minute land surface composite dataset is derived from data collected at sites with 5 minutes or less resolution (about 120 sites). The storm-fest hourly land surface composite dataset is derived from data collected at all 1-hour resolution sites (about 720 sites).

The STORM-FEST operational period (February 1 - March 15, 1992) is available online.

The STORM-FEST composite datasets second release (version 2) for surface observations is now available. The composites are available as hourly and 5-minute datasets separated into daily files. The files consist of several surface parameters, 1 station observation per record, and are sorted by time, station latitude, and station longitude. Version 2 contains pam humidity data, pam boundary layer (1-minute) stations, and 1-minute data from Iowa AWOS stations in the 5-minute composite and replace information for these stations in the hourly composite. Manual quality control was performed on selected hourly values. The 5-minute surface composite dataset contains data from the PAM network, ASOS network, Illinois State Water Survey Network, and PROFS Network. The hourly surface composite dataset contains additional data from AWOS network, Nebraska High Plains Climate Network, Wind Profiler Demonstration Network, and the NOAA/NESDIS National Climatic Data Center (NCDC) Surface Airways Observations (TD-3280).

The 'composite format' applies to both the hourly and 5-minute composites with one variation. The hourly composite dataset contains the nominal date and time of observation, whereas the 5-minute composite does not. The nominal date and time is the nearest top of the hour time for the observation as compared to the actual time of the observation. Most networks actually take the observation about 5-minutes before the hour, but this varies from network to network and station to station in a network. The parameters include nominal date of observation, nominal time of observation, actual date of observation, actual time of observation, network identifier, station identifier, latitude, longitude, station occurrence, station elevation, station pressure, reported sea level pressure, computed sea level pressure, dry-bulb temperature, dew point, wind speed, wind direction, total precipitation, squall/gust indicator, squall/gust value, present weather, visibility, and ceiling height, flag, and amount for the first, second, and third layers.

Parameter Notes:

1. The nominal date and time differs from actual time. It is the actual time rounded to the nearest hour for the hourly dataset and rounded to the nearest quarter hour for the 5-minute dataset. Actual times may vary a few minutes before or after nominal time. Actual times are not included in the dataset.

2. The nominal date and time is included only in the hourly composite. The 5-minute composite begins with actual date and time.

3. The station occurance is a uniqueness code to separate two different stations that may be co-located in the same latitude/longitude point.

4. Not all platforms report these parameters. If not available for a network the value was set to missing and the QC flag to "not observed".

This record provides a listing of meteorological data collected in the Australian Antarctic Territory by members of the Australian Antarctic program (and it's predecessors) and the Bureau of Meteorology. The data have been obtained by manual observations and by automatic weather stations.

All data are available from the Bureau of Meteorology, and are considered to be the authoritative source of weather data in the Australian Antarctic Territory (as they have been quality checked). Raw data directly from the automatic weather stations at the stations is available at https://data.aad.gov.au/aws.

The data available here includes:

• Automatic Weather Station data from 7 sites - Casey, Davis, Macquarie Island, Mawson, Wilkins, Davis Whoop Whoop, and Casey Skiway South. Data resolution varies, but is approximately every 30 minutes.

• Daily weather data from 48 sites. Note - not all of these sites are still operational.

• Synoptic weather data from 53 sites. Note - not all of these sites are still operational.

• Terrestrial soil data from 4 sites. Note - not all of these sites are still operational.

• Upper air data from 5 sites. Note - not all of these sites are still operational.

• High resolution, 1 minute automatic weather station data from 7 sites - Casey, Davis, Macquarie Island, Mawson, Wilkins, Davis Whoop Whoop, and Casey Skiway South.

• Daily and Synoptic data from a number of decommissioned sites.

Site details of 24 sites. For full site listings, seeing the file for station details within each dataset ("HM01X_StnDet").
