Aerosol-cloud interactions in the NASA GMI: model development and indirect forcing assessments

Interactive comment on “Aerosol-cloud interactions in the NASA GMI: model development and indirect forcing assessments” by N. Meskhidze et al

1. This study investigates the influence of varying meteorological fields and cloud droplet parameterizations on the aerosol indirect effect (AIE). While I know of previous studies comparing various droplet parameterizations, investigating the effect of varying the meteorology on the AIE is potentially more interesting. I also find the NASA GMI concept, where various model components can be int...

The NASA Micro-Pulse Lidar Network (MPLNET): an overview and recent results MPLNET, Red de lidares Micro-pulso de la NASA: Descripción general y resultados recientes

We present the formation of a global ground-based eye-safe lidar network, the NASA Micro-Pulse Lidar Network (MPLNET) – founded in 2000. The aim of MPLNET is to acquire long-term observations of aerosol and cloud vertical profiles at unique geographic sites collocated with sunphotometers in the NASA Aerosol Robotic Network (AERONET). These joint MPLNET/AERONET sites collect data on aerosol and ...

CALIPSO: Global aerosol and cloud observations from lidar and passive instruments

CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Spaceborne Observations) is an approved satellite mission being developed through collaboration between NASA and the French space agency CNES. The mission is scheduled for launch in 2004 and will operate for 3 years as part of a five-satellite formation called the Aqua constellation. This constellation will provide a unique data set on aeroso...

Evaluation of aerosol-cloud interaction in the GISS ModelE using ARM observations

[1] Observations from the US Department of Energy’s Atmospheric Radiation Measurement (ARM) program are used to evaluate the ability of the NASA GISS ModelE global climate model in reproducing observed interactions between aerosols and clouds. Included in the evaluation are comparisons of basic meteorology and aerosol properties, droplet activation, effective radius parameterizations, and surfa...
