The Hugo Island Automatic Weather Station is installed on a small island adjacent to Hugo Island along the West Antarctic Peninsula (64.963°S, 65.669°W). The station is mounted at approximately 27 m above sea level. Data is saved every 10 minutes. Data column descriptions are listed below.
Data Column | Variable | Units or Format | Comments
The time stamp is that of the end of the 10-min measurement interval for each data point.
- 3 | Voltage of Internal Recorder Battery | volts
Minimum voltage measured during the 10-min interval.
- 4 | Internal temperature of recorder | degrees Celsius
The internal panel temperature (inside data logger, field 4) is a 10 minute average of 5 second samples.
- 5 | Voltage of the AWS Battery Pack | volts
Minimum voltage measured during the 10-min interval.
- 6 | Atmospheric Temperature | degrees Celsius
10-min average of samples every 5 seconds.
- 7 | Atmospheric Pressure | millibar
This is a sample average during a 1-min measurement period at minute 6 of each measurement interval. This variable is adjusted to sea level using an offset.
- 8 | Wind Speed | meters per second
10-min average of samples every 5 seconds.
- 9 | Wind Direction | degrees
10-min average of samples every 5 seconds. Measured in meteorological convention (i.e,, 0 degrees is wind from the north, 90 degrees is winds from the east). Direction is nearly geographical, as sensor was oriented to correct a 19 degrees east local magnetic declination. Users should consider further drift in the declination.
Maximum wind speed during the measuring interval (10 min)
- 12 | Gust Time | “Y-M-d H:M:S”
Date/Time of Gust Speed measurement.
