The weather data was obtained from the following
five sources: (1)
The National Climatic Data Center (NCDC)
of the National
Oceanographic and Atmospheric Administration (NOAA), (2) COOP
Stations, (3) Meteorological Aviation Report (METAR), (4) Crop Weather Program
Weather Station Network at
Texas, and (5) Beaumont/Eagle Lake research weather stations
Quality Control. A vigorous program was
used to check for data errors and estimate missing data points. A linear
interpolation method is used to estimate ten or fewer consecutive missing
data points for the following weather measurements: temperature, relative
humidity, wind speed, wind direction, solar radiation, and ET0.
Since rainfall does not follow any pattern, missing rainfall data will be
flagged as missing. For ten days to 4 months of consecutive missing
data points, we use historic average weather data and adjust it
proportionally with the current average for the adjacent period. Historic
average is calculated based on past 30 years (minimum of 5 years) of data by
excluding invalid and missing data points.
Weather Data Update.
automatically retrieves weather data from the above five data sources for all
available weather stations, pass the retrieved data through the quality control
program and store the filtered data in our weather database.
The NOAA weather data is usually 1-2 months old when it is available to
us. The remaining four sources provide near real-time weather data with just
one to three days of delay
Filter. Active: Display only
