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".
