Weather data collection

Hourly weather data for all the 19 sites were collected using the National Centers for Environmental Information (NCEI) National Oceanic and Atmospheric Administration (NOAA) Integrated Surface Database (ISD). The ISD Lite version was used for easy hourly data capture.

Weather data files

• The format of the raw data from the ISD-Lite is documented here. Following processed attributes are there in each weather file:

  • timestamp
  • air temperature (no scaling, degrees C)
  • dew point temperature (no scaling, degrees C)
  • sea level pressure (no scaling, hectopascals)
  • wind direction
  • wind speed rate (no scaling, m/s)
  • cloud coverage
  • liquid precipitation depth (1 hour)
  • liquid precipitation depth (6 hour)

• Missing values are processed to be 'NaN' instead of -9999 as per the raw data

• More details about each attribute can be found here.
