Lidar Atmospheric Sensing Experiment

Project Description
The Lidar Atmospheric Sensing Experiment (LASE) program was initiated
as an effort to produce an autonomous system for measuring water vapor
levels from airborne and spaceborne platforms using LIDAR technology.

Objectives include:

1. Develop and demonstrate autonomous DIAL systems from airborne
and spaceborne platforms.

2. Measure water vapor, aerosol, and cloud profiles from a high
altitude extended range U-2 (ER-2) aircraft.

Use of experiment:

1. Studies of air mass modification
2. Studies of latent heatflux
3. Studies of the water vapor component of the hydrological
cycle
4. Studies of atmospheric transport using water vapor as a
tracer of atmospheric motions

The simultaneous measurement of aerosol and cloud distributions can
provide important information on atmospheric structure and transport,
and many meteorological parameters can also be inferred from these
data. In addition, the impact of subvisible and visible aerosol/cloud
layers on passive satellite measurements and radiation budgets can be
assessed. The atmospheric science investigations that can be conducted
with LASE are greatly enhanced because measurements of water vapor
profiles and column content are made simultaneously with aerosol and
cloud distributions
