Ground Based Remote Sensing LSOS and Fall Campaign Overview
* Terrestrial Lidar Systems (TLS)- VZ400, VZ1000, VZ4000, C10
* Survey grade GPS- all stakes, some road intersections, building corners, etc.
* Microwave Radiometers- 1.4, 19, 37 GHz
* Radar- 1 GHz
* Optical - Sun photometer (at LSOS and SB/SASP)
* Other techniques- Time-lapse cameras- Tree accelerometers- GPS antennas- High speed camera for falling particles
More instruments will be used in February(e.g. ASD spectroradiometers, mobile radars, scatterometers)

Update on Winter Participation• Dorothy: only ~half of people contacted have
responded• Deadline tomorrow 9/16/16• Kelly: critical to get your response; holding up
the overall personnel logistics planning of entire winter campaign
• Ed: reason is the only way to accommodate the community participation levels everyone wants is to have participants come in shifts
