DSI-3292: Weather Duration
NCDC Dataset Documentation for DSI-3292
information
Weather Duration is historical digital data set DSI-3292,
archived at the National Climatic Data Center (NCDC). This is
meteorological data. DSI-3292 contains the beginning and ending times
of occurrences of weather and/or obstructions to vision that were
recorded on the MF1-10B form used by the National Weather Service (NWS).
Official surface weather observation standards can be found in the
Federal Meteorological Handbook. This data set is most useful if
coordinated with data for the same stations and dates in NCDC digital
data set DSI-3280, US Global Surface Airways Hourly Observations.
DSI-3292 includes data from 1984 to 1997. NCDC has data for 299
stations. Areal coverage includes the US, Puerto Rico, Guam, American
Samoa, and the Pacific Ocean nations of Palau, Marshall Islands and
Micronesia
To make a wide range of climatic data available to researchers and the
public.

00000000-00099999. Five digit station numbers are always right justified
zero filled.
Positions 12-15: Element-Type The type of data element stored in this record. Hourly
weather occurrence data (this field will always be "WTHR"). This is the
only element type in this data file.
Hourly weather occurrence data (present weather codes) are described in
positions 39 - 40 below.
Positions 16-17: Element-units This field not applicable for weather occurrence elements.
This field will always be 'NA'.
Positions 18-21: Year
This is the year of the record. Range of value is 1984 - current year.

Positions 26-27: Day
This is the day of record. Range is 01-31.
Positions 28-30: NUM-VALUES
The actual number of values recorded in the data section of the record. Range
of values is 001-100.
Note: All positions after 30 are the data section. The number of data values
is the data section is NUM-VALUES. Each data value is a block consisting of
12 characters. Positions 31-42, which comprise the first 12-character data
value block, are described below. The same description applies to all blocks.
A record may contain fewer or more data values than you might expect. There
may be only one data value, or there may be data values for all possible times
of observation. Also, there may be additional data values created due to
the fact that, when erroneous data is encountered during quality control, the
original data values are flagged as errors and may be followed by replacement
values (see Flag-1 and Flag-2 for details).
Positions 31-34: BEG-TIME-OF-VALUE
The beginning time in hour and minutes of the occurrence of weather (Present
Weather).Range is 0000-2359, 8888, and 9999. Missing or unknown is recorded
as '9999'.
NOTE: Check Flag-1 at all times. When Flag-1 = 'B', the beginning value will
equal the hour-minute the weather occurrence began, but the ending time will
be set to '8888'.
When Flag-1 = 'C', both beginning and ending values will be set to '8888'
indicating that the weather occurrence is continuing from a previous day and
occurring throughout the entire present day.
Positions 35-38: ENDING-TIME-OF-VALUE
The ending time in hour and minutes of the occurrence of weather. (present
weather). Range is 0000-2359, 8888, and 9999. Missing or unknown is recorded
as '9999'.
NOTE: Check Flag-1 at all times. When Flag-1 = 'E', ending time will be set
to equal the hour-minute that the weather occurrence ended, but the beginning
time value will be set to '8888'.
When Flag-1 = "C" both beginning and ending times will be set to '8888'
indicating that the weather occurrence is continuing from a previous day and
occurring throughout the entire present day.
Positions 39-40: PRESENT WEATHER

characters in length. The leftmost digit indicates the general class of
present weather while the rightmost digit qualifies weather severity.

Position 41: FLAG-1 FLAG-1 is a data measurement flag.
B = Beginning of continuous period.
E = End of continuous period from previous day.
C = Continuous throughout present day (from previous day).
b = (blank) occurrence began and ended on this day.
NOTE: When FLAG-1 = B, the beginning time will equal the hour-minute that the
weather occurrence began but the ending time will be set to '8888'.
When FLAG-1 = E, the ending time will equal the hour-minute that the weather
occurrence ended but the beginning time will be set to '8888'.
When FLAG-1 = C, both the beginning and ending times will be set to '8888'
indicating that the weather occurrence is continuing from a previous day and
occurring for the entire present day.
Position 42: FLAG-2 FLAG-2 is a data quality flag.
0 = Observed data has passed all internal consistency checks.
1 = Validity indeterminable
2 = Observed data has failed internal consistency check
(Subsequent edited value follows observed value).
3 = Observed data has failed internal consistency check (no
subsequent edited value follows).
4 = Observed data value invalid (no edited value follows).
E = Edited data value passes all system checks (no observed
value is present).
S = Manually edited data value (passes all system checks).
* Data groups continue in the same form as positions 31-42 repeated as many
times as needed to contain one day of record. Maximum number of occurrences
which occur in one 24-hour day is 100.
