Sarah PCWS unmodified ten-minute observational data, 2020 - present (ongoing).

These files contain observations at ten-minute intervals, in a comma delineated format. The data are the original transmitted observations with no error checking executed. There may be bad observations in the dataset.

There is no header on the datafiles. The CSV columns in order are:

  1. YYYY-MM-DD HH:MM:SS real-time (UTC)
  2. PRT Average Temperature (C)
  3. PRT Instantaneous Temperature (C)
  4. Thermistor 1 Average Temperature (C)
  5. Thermistor 1 Instantaneous Temperature (C)
  6. Thermistor 2 Average Temperature (C)
  7. Thermistor 2 Instantaneous Temperature (C)
  8. Thermistor 3 (lower) Average Temperature (C)
  9. Thermistor 3 (lower) Instanteneous Temperature (C)
  10. Paroscientific board temperature (C)
  11. Paroscientific pressure (hPa)
  12. Average Temperature from HMP155 RH (C)
  13. Relative Humidity Average from HMP155 (%)
  14. Instantaneous Temperature from HMP155 RH (C)
  15. Instantaneous Relative Humidity from HMP155 (%)
  16. Wind speed, 2 minute average (m/s)
  17. Wind direction, 2 minute average (degrees)
  18. Wind speed, standard deviation (m/s)
  19. Wind direction, standard deviation (degrees)
  20. Gust speed, 2.5 second gust (m/s)
  21. Gust direction (degrees)
  22. Wind speed, instantaneous, 5 seconds prior to transmission (m/s)
  23. Wind direction, instantaneous (degrees)

All times listed are UTC and missing data are not indicated. Wind directions listed are the direction the wind is blowing from, from 0 to 360 clockwise (thus 90 degrees is east, 180 is south and 270 is west.) The data is in the following units: temperatures in degrees Celsius, station pressure in millibars, wind speed in meters per second, wind direction in meteorological degrees, and relative humidity in percent.

The data here is the raw, uncorrected data we receive. No bad data have been removed, though calibration errors may result in the re-generation of some of the data.
