Today the skies are clear. PALS is flying again today, and also flew on June 12th. So this is the third PALS flight day.

There is hardly a cloud in sight anywhere as PALS takes off. The soil moisture sampling crews are out. To get an update on the status of the data acquisitions (PALS and ground data) you can go to the SMAPVEX12 web page and click on "status of aircraft observations and field sampling".

Mariko and her team have sent in some beautiful photos of the forest sites. So here they are.

The forest sites are marked in red on the image at right, numbered F1 to F5 starting from the top. The sites fall along one of the low-altitude PALS/Twin Otter flight lines. In the photo captions F2 S1 refers to forest site 2 sampling location 1, etc.

F2 S1: Mariko at easternmost point. Very clay-rich soil in marshy vegetation (6/7/2012).
Kaighin with the best soil extraction of the day.
F1 S1 Vanessa at center of transect: Core sampling + leaf litter / organic soil sample extraction (6/7/2012).
F2 S1 center of transect: Core sampling + leaf litter / organic soil sample extraction (6/7/2012).
Happiness is field sampling.
F2 S1 Kaighin and Parag, hard labor? (6/7/2012).
Pasture just outside F2 has to be crossed to enter the site. Approximate distance from car to entrance of site is about 300 meters (Day 1: 6/7/2012).
