Dataset Identification:
Resource Abstract:
- description: Global Surface Summary of the Day is derived from The Integrated Surface Hourly (ISH) dataset. The ISH dataset
includes global data obtained from the USAF Climatology Center, located in the Federal Climate Complex with NCDC. The latest
daily summary data are normally available 1-2 days after the date-time of the observations used in the daily summaries. The
online data files begin with 1929 and are at the time of this writing at the Version 8 software level. Over 9000 stations'
data are typically available. The daily elements included in the dataset (as available from each station) are: Mean temperature
(.1 Fahrenheit) Mean dew point (.1 Fahrenheit) Mean sea level pressure (.1 mb) Mean station pressure (.1 mb) Mean visibility
(.1 miles) Mean wind speed (.1 knots) Maximum sustained wind speed (.1 knots) Maximum wind gust (.1 knots) Maximum temperature
(.1 Fahrenheit) Minimum temperature (.1 Fahrenheit) Precipitation amount (.01 inches) Snow depth (.1 inches) Indicator for
occurrence of: Fog, Rain or Drizzle, Snow or Ice Pellets, Hail, Thunder, Tornado/Funnel Cloud Global summary of day data for
18 surface meteorological elements are derived from the synoptic/hourly observations contained in USAF DATSAV3 Surface data
and Federal Climate Complex Integrated Surface Hourly (ISH). Historical data are generally available for 1929 to the present,
with data from 1973 to the present being the most complete. For some periods, one or more countries' data may not be
available due to data restrictions or communications problems. In deriving the summary of day data, a minimum of 4 observations
for the day must be present (allows for stations which report 4 synoptic observations/day). Since the data are converted to
constant units (e.g, knots), slight rounding error from the originally reported values may occur (e.g, 9.9 instead of 10.0).
The mean daily values described below are based on the hours of operation for the station. For some stations/countries, the
visibility will sometimes 'cluster' around a value (such as 10 miles) due to the practice of not reporting visibilities
greater than certain distances. The daily extremes and totals--maximum wind gust, precipitation amount, and snow depth--will
only appear if the station reports the data sufficiently to provide a valid value. Therefore, these three elements will appear
less frequently than other values. Also, these elements are derived from the stations' reports during the day, and may
comprise a 24-hour period which includes a portion of the previous day. The data are reported and summarized based on Greenwich
Mean Time (GMT, 0000Z - 2359Z) since the original synoptic/hourly data are reported and based on GMT.; abstract: Global Surface
