December 2011 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).
