Yesterday I visited Gwangneung site. It was snowy/rainy, sunny, cloudy, windy and calm.

The weather condition dynamically changed.

Leaves of understory (and a few overstory trees) started to unfold (see Fig. 1 & 2).

Needleleaf trees were planted at the north slope in GCK (see Fig. 3). 

The trees might be planted on Arbor Day (by President Park and the others). 

I think that it can be a fascinating research object. 

In GDK,

Corrected the wrong wiring (ECO_CR1000 to AM16/32B)

Corrected leveling of the cup anemometer at 20 m

Calibrated profile system

Collected data (including CF cards in EC_CR3000 and SEB_CR5000)

In GCK,

Move the LED sensor at 19.5 m to 22.5 m (worked with Galam)

Fixed TC of profile system at the LV. 5

Collected data (including CF card in EC_CR3000)
