data basics

Data used to come in files ordered like this:

ID M D T P Strain Res TX TY TZ

10 12 2 0 6.89473 0.658301 20.2287 -3.84744 -11.3207 71.934

New system should do something like this:

YYYY MM DD time ID T P Str Res TX TY TZ refl

note TiltZ is separate (ie not X2) for 2008

Battery Volts may be fetched separately daily as part of a probe status packet

Need to integrate all probe data. Beware that the Java plots and some excel shows P as water pressure height equiv. not Pa. Our pressures are hundreds of kPa.

1psi = 0.068046atm = 6.894733 kPa, so 100psi guage goes up to 70m water pressure

Weather

needs to be downloaded from: http://en.vedur.is/weather/forecasts/areas/eastfjords/#group=18&view=table

We have an agreement for an XML feed from: http://en.vedur.is/weather/observations/areas/southeast/#station=705

Wunderground data can be obtained automatically using this kind of url

http://www.wunderground.com/weatherstation/WXDailyHistory.asp?ID=IHEDMARK3&month=10&day=1&year=2006&format=1

you need to ID of the station you want - and this gives comma separated data

we need weather data from iceland weather service

Just set up webcam daily download (at 12:15) to http://leo.ecs.soton.ac.uk/data/glacsweb/iceland/webcam/hofn/


leo is the database and web server where all data will be stored.
