Of things you can fix this trip:

Franklin Bluffs - 3 meter Relative Humidity should be replaced

Program isn't properly measuring LW thermistors, at least the part outputted in the meteorological data array

Sagwon -- Look for a loose wire on the 10 meter air temperature.

West Kuparuk -- Maybe a bad charge controller or a wiring panel that needs replacing.

Imnavait Basin New -- 3 meter wind speed isn't working most of the time.

All Sensors look decent.  The exception is net radiation but that will be pulled now so it doesn't really matter at present.

All Sensors look decent.

3m Relative Humidity still needs to be switched out.  See how high it is over 100% in summer by clicking on the picture.

Other Met look good.

One LW sensor looks not good this year.

There is a place holder in the output array for the Longwave dome thermistors however nothing is being recorded (one is zero the other is -6999).

Soil Temperatures look good.

''Meteorological''

Check for a loose wire on the 10 meter air temperature.  Good most of the time but some bad data this summer a couple times. (10m RH looks fine)
Reflected SW doesn't look like it worked this year.

Soil Temperatures look good

=West Kuparuk=

''Soil Temperatures''

Maybe a loose wire on the multiplexer for the soil temperature sensors.  Started 6/26/08 and have had some good data briefly in early August but otherwise the data is bad... after seeing the bad stuff in Meteorological I am inclined to think it's a logger problem maybe from that static issue that hit another site.

''Meteorological''

Looks like something strange beginning on 6/25/08.  Sensors begin to read correctly again on 7/30/08 (after the station visit) and then are spotty beginning 8/11/08.  Not sure the deal but my money would be on replacing the charge controller and the wiring panel.  But, importantly, there appears to be good data mixed in with the bad so I don't think it's bear damage.

  Affected sensors:
  AT/RH @ 1m, 3m, 10m
  Longwave Radiation
  Shortwave Radiation
  Battery Voltage
  Panel Temperature
  Precipitation
  Net Radiation

=Upper Kuparuk Met=

LW Radiation records as zero all summer
All other Meterological stuff looks good.

Soil Temperatures Look Good

You'll probably have to click on the image but it looks like the 3 meter wind speed is only working part time.  

All the other meteorological sensors look good.
