January 1994 Daily Weather Data: What the table headers means?
Notes: - Missing station name, etc indicate the metadata are not currently available. - The term "bogus" indicates that the station name, etc are not available. - The 99999 indicates that the value is not available. . Explanation of table headers: FIELD TYPE DESCRIPTION Temper. Real Mean temperature for the day in degrees Fahrenheit / Celcius to tenths. Missing = 9999.9 Dew Point Real Mean dew point for the day in degrees Fahrenheit to tenths. Missing = 9999.9 Sea Real Mean sea level pressure for the day in millibars to tenths. Missing = 9999.9 Level Pressure Station Real Mean station pressure for the day in millibars to tenths. Missing = 9999.9 Pressure Visibility Real Mean visibility for the day in miles to tenths. Missing = 999.9 Wind Speed Real Mean wind speed for the day in knots to tenths. Missing = 999.9 Maximum Sust. Real Maximum sustained wind speed reported Wind for the day in knots to tenths. Speed Missing = 999.9 Maximum Real Maximum wind gust reported for the day Wind in knots to tenths. Missing = 999.9 Gust Maximum Real Maximum temperature reported during the Temper. day in Fahrenheit / Celcius to tenths--time of max temp report varies by country and region, so this will sometimes not be the max for the calendar day. Missing = 9999.9 Flag Char Blank indicates max temp was taken from the explicit max temp report and not from the 'hourly' data. * indicates max temp was derived from the hourly data (i.e., highest hourly or synoptic-reported temperature). Minimum Real Minimum temperature reported during the Temper. day in Fahrenheit / Celcius to tenths--time of min temp report varies by country and region, so this will sometimes not be the min for the calendar day. Missing = 9999.9 Flag Char Blank indicates min temp was taken from the explicit min temp report and not from the 'hourly' data. * indicates min temp was derived from the hourly data (i.e., lowest hourly or synoptic-reported temperature). Total Real Total precipitation (rain and/or melted Precip. snow) reported during the day in inches and hundredths; will usually not end with the midnight observation--i.e., may include latter part of previous day. .00 indicates no measurable precipitation (includes a trace). Missing = 99.99 Note: Many stations do not report '0' on days with no precipitation--therefore, '99.99' will often appear on these days. Also, for example, a station may only report a 6-hour amount for the period during which rain fell. See Flag field for source of data. Flag Char A = 1 report of 6-hour precipitation amount. B = Summation of 2 reports of 6-hour precipitation amount. C = Summation of 3 reports of 6-hour precipitation amount. D = Summation of 4 reports of 6-hour precipitation amount. E = 1 report of 12-hour precipitation amount. F = Summation of 2 reports of 12-hour precipitation amount. G = 1 report of 24-hour precipitation amount. H = Station reported '0' as the amount for the day (eg, from 6-hour reports), but also reported at least one occurrence of precipitation in hourly observations--this could indicate a trace occurred, but should be considered as incomplete data for the day. I = Station did not report any precip data for the day and did not report any occurrences of precipitation in its hourly observations--it's still possible that precip occurred but was not reported. Snow Depth Real Snow depth in inches to tenths--last report for the day if reported more than once. Missing = 999.9 Note: Most stations do not report '0' on days with no snow on the ground--therefore, '999.9' will often appear on these days. Ind. Int. Indicators (1 = yes, 0 = no/not reported) for the occurrence during the day of: Fog ('F' - 1st digit). Rain or Drizzle ('R' - 2nd digit). Snow or Ice Pellets ('S' - 3rd digit). Hail ('H' - 4th digit). Thunder ('T' - 5th digit). Tornado or Funnel Cloud ('T' - 6th digit).
