Overview

Nine PAM stations were deployed in support of FLAT90, primarily to estimate the amount of divergence or convergence of the flow around the ASTER site. See the ASTER Report for more information.

Data Access

PAM data are available here in Common Mesonet Format (CMF).

Location

The stations were deployed in a 3x3 array, spaced approximately 2 miles around the ASTER site:

Site  Lat      Lon        Alt (m)
1     41.1000 -104.3328   1662
2     41.1000 -104.2917   1641
3     41.1000 -104.2539   1629
4     41.0708 -104.3325   1655
5     41.0697 -104.2922   1641
6     41.0697 -104.2547   1627
7     41.0422 -104.3317   1648
8     41.0428 -104.2933   1635
9     41.0428 -104.2539   1623
ASTER 41.0668 -104.2966    -

Sensors

All sites had:

Barometer
Temperature/humidity (wet-bulb) at 2m
2-orthogonal propellers at 10m
Rain gauge (tipping bucket)

In addition, site 5 had extra sensors:

Radiometric surface temperature
Soil temperature (2)
Reflected solar radiation
Net radiation
Incoming infrared radiation

(I'm not sure why stations 6,8,9 had one fewer variable in my reprocessed files.)

A theodolite was used to set the station orientation, so the wind directions should be much better than 1 degree.
