A sub-tropical cirrus clouds climatology from Reunion Island (21°S, 55°E) lidar data set

Long-term trend analysis and climatology of tropical cirrus clouds using 16 years of lidar data set over Southern India

Sixteen-year (1998–2013) climatology of cirrus clouds and their macrophysical (base height, top height and geometrical thickness) and optical properties (cloud optical thickness) observed using a ground-based lidar over Gadanki (13.5 N, 79.2 E), India, is presented. The climatology obtained from the ground-based lidar is compared with the climatology obtained from 7 and a half years (June 2006–...

Midlatitude Cirrus Clouds and Multiple Tropopauses from a 2002-2006 Climatology over the SIRTA Observatory

This study present a comparison of lidar observations of midlatitude cirrus clouds over the SIRTA observatory between 2002 and 2006 with multiple tropopauses (MT) retrieved from radiosounding temperature profiles. The temporal variability of MT properties (frequency, thickness) are discussed. Results show a marked annual cycle, with MT frequency reaching its lowest point in May (~18% occurrence...

The Optical Properties of Tropical Cirrus Clouds in the Maritime Continent Thunderstorm Experiment from Lidar and Infrared Radiometer Retrievals

The Maritime Continent Thunderstorm Experiment (MCTEX) provided another opportunity to study tropical cirrus and anvil clouds. The component of the experiment that included the lidar and radars was supported by the ARM Program. The experiment has provided a further set of data to categorize tropical cirrus in terms of their cloud-radiation interactions, a central theme of the ARM Program. The d...
