ISCCP ON-LINE DATA FOR GEWEX CLOUD SYSTEM STUDY

WORKING GROUP 3 (EXTRATROPICAL LAYERED CLOUD) EXPERIMENTS


WISP | CFRP III | CASP II | BASE | FRONTS 92 | FASTEX


(SAMPLE

The Winter Icing and Storms Project (WISP) field studies were conducted in the Colorado Front Range area over a period of two years. The main goals of this project are to study the processes leading to the formation and depletion of supercooled liquid water in winter storms and to improve forecasts of aircraft icing. The data presented here are from three days (March 12-14) during the 1990 campaign. During these days a shallow cold front crossed the field study area.


(SAMPLE

The Australian Cold Front Research Project (CFRP) Phase III case study focused on a cool change passage that took place over the south coast of Australia (approximate area 47S-27S latitude, 125E-157E longitude) over the time period November 17-19, 1984.


(SAMPLE

The Canadian Atlantic Storms Program (CASP) II was conducted near the Avalon Peninsula of Newfoundland, Canada, from 15 January through 15 March 1992 to improve understanding and prediction of the mesoscale structure of east coast storms and to improve understanding of the interaction between the atmosphere, ocean and sea ice (Stewart, R.E., 1991: Canadian Atlantic Storms Program: Progress and Plans of the Meteorological Component, Bull. Amer. Meteor. Soc.,72,364-371). Data were collected from aircraft, the local meteorological network, a special "mesonet", and Doppler radar. The experimental region is from 35N-55N latitude and 40W-80W longitude. There were 16 Intensive Observing Periods: this case occurred on 26-27 February 1992.


(SAMPLE

The Beaufort and Arctic Storms Experiment (BASE) study was a Canadian-led international field campaign to study the weather systems occurring in southern Beaufort Sea and surrounding areas of the Arctic near the outlet of the MacKenzie River. A combination of two aircraft, two Dopler radars, enhanced rawinsonde and other surface weather observations made measurements from 1 September through 13 October 1994 to understand weather systems, their clouds and their impact on the regional climate of the MacKenzie River Basin. The experimental region extends approximately from 60N to 75N latitude and from 210E to 230E longitude. The BASE Project Homepage provides further information on BASE and the availability of data collected.


(SAMPLE

The Fronts 92 field experiment took place in the Eastern North Atlantic with the objective to study the dynamics of frontal systems in the region. The data presented here are from the third Intensive Observation Period (IOP) that took place on April 27th and 28th 1992. During this period a rapidly developing cold frontal wave crossed the field experiment area. The experimental region extends approximately from 30N to 60N latitude and from 50W to 10E longitude.


(SAMPLE

The Fastex field experiment took place in January and February 1997 and studied midaltitude storms in the Eastern North Atlantic region. The data presented here are from February 1997 and cover a region from 30N to 65N latitude and from 60W to 5E longitude.
