IRTF Weather Data
The weather data collected around the IRTF is located in weather.txt and this file is generated as part of the IQUP data collection, via a script run by cron every minute on duke.
The file contains the following data:
- TIMESTAMP1, unix timestamp for the data
- TIMESTAMP2, human-readable format of TIMESTAMP1
- TELESCOPE, telescope identifier
- TE1, temperature in C, top of the IRTF dome
- TE2, temperature in C, top of the IRTF dome
- TE3, temperature in C, west side of IRTF roof
- HE1, humidity, top of the IRTF dome
- HE2, humidity, west side of IRTF roof
- WDIR1, wind direction in degrees from north, on external fan room roof west of IRTF
- MDNWSD1, median windspeed over two minutes in mph, on external fan room roof west of IRTF
- AVGWSP1, average windspeed over two minutes in mph, on external fan room roof west of IRTF
- MINWSP1, minimum windspeed over two minutes in mph, on external fan room roof west of IRTF
- MAXWSP1, maximum windspeed over two minutes in mph, on external fan room roof west of IRTF
- WDIR2, wind direction in degrees from north, sensor not connected
