Met station
From Glacsweb Wiki
- Local met station needed
- Hofn is a good backup but is 20km away!
- Akurnes also gives us weather data via wunderground
- mountain cafe may be best site
- Davis has been bought and tested
- Davis Comparison very little info comparing it with research grade weather stations.
- Local temperature sensors (one for base too)
- precision thermistor looks good but would need custom interface
- Pt Resistance Thermistor would rather use something a bit more accurate if possible - it not much more compared to the other costs...
- Campbell Scientific 107 (version used by met office) is £48 w 3m cable. Radiation shield for £78.
- if we use a pt100 - what adc conditioning circuit do we need?
- something like the 4 wire design here? (with different amp for air temp range) Media:Signal conditioning for pt100.pdf
- if we use a pt100 - what adc conditioning circuit do we need?
- autonomous sensor/logger If we're not worried about having data in realtime one of these (or something similar) would be good. ~£150 with calibration certificate and it'll do hourly temperature measurements for over two years.
need to look into other free software eg this one
