Ice nucleation and cloud microphysical properties in tropical tropopause layer cirrus
Ice nucleation cloud microphysical properties tropical tropopause layer cirrus
2010/2/21
In past modeling studies, it has generally been assumed that the predominant mechanism for nucleation of ice in the uppermost troposphere is homogeneous freezing of aqueous aerosols. However, recent i...
Fractional release factors of long-lived halogenated organic compounds in the tropical stratosphere
Fractional release factors halogenated organic compounds tropical stratosphere
2010/2/21
Fractional release factors (FRFs) of organic trace gases are time-independent quantities that influence the calculation of Global Warming Potentials and Ozone Depletion Potentials. We present the firs...

Annual cycle of ozone at and above the tropical tropopause: observations versus simulations with the Chemical Lagrangian Model of the Stratosphere (CLaMS)
Annual cycle tropical tropopause Chemical Lagrangian Model Stratosphere CLaMS
2010/1/18
Multi-annual simulations with the Chemical Lagrangian Model of the Stratosphere (CLaMS) were conducted to study the seasonality of O3 within the stratospheric part of the tropical tropopause layer (TT...
Study of successive contrasting monsoons (2001–2002) in terms of aerosol variability over a tropical station Pune, India
successive contrasting monsoons aerosol variability tropical station Pune
2010/1/18
The present study suggests that aerosols play a major role in cloud formation and affect significantly the precipitation over a regional scale. The study reveals that there is a high variability of ae...
