Subject:
OLI/MASC/M1 - Missing instrument data possible
DataStreams:olimascM1.00, olimascM1.a1, olimascM1.b1
Description:
The MASC instrument has been installed on a pole on the corner of a connex container roof. 
The location is preliminary for this season, it causes aerodynamic problems. During 
windy situations (almost all the time during snowfall up in Oliktok) there is probably a kind 
of swirl forming and the snowflakes are concentrated around the margins of the inlet 
ring. Triggering only occurs when snowflakes pass close to the center of the ring. The 
location atop the container is obstructed and results in a loss of data. Double fence wind 
shielding is proposed for the following seasons. A move of the MASC to an unobstructed 
location away from the containers and installation of wind shielding is planned once the 
weather conditions are more favorable the latest in fall 2016.
Suggestions: 
Please take missing snowflake data into account.
