The mysterious effect of aerosols and clouds on the dynamics
of our atmosphere has become a critical focus of research in
the last several years. The recent CALIPSO And Twilight Zone (CATZ)
experiments combined multiple sources of data to learn more about
the role that clouds and aerosols play in our atmosphere.
While flying up the Eastern Seaboard on the B-200 King Air,
HSRL took measurements in coordination with CALIPSO satellite
data and strategically placed AErosol RObotic NETwork (AERONET)
remote sensing stations. Each data source provided a different
perspective of the same point in the atmosphere, ultimately contributing
to a better understanding of the cloud-aerosol continuum,
also known as the twilight zone.
Because flight paths must be aligned with a CALIPSO flyover
of the ground-based AERONET sites, researchers working on the CATZ
experiments were able to utilize the days in between CATZ flights for
other experimental objectives. The B-200 crew used these valuable moments
to take as many readings with HSRL as possible, including gathering
over-ocean data, and flying CALIPSO and Moderate
Resolution Imaging Spectroradiometer (MODIS) validation flights.
