The Megha-Tropiques mission has been operating since 12 October 2011 and serves research and operational objectives related to the tropical water and energy cycle as mentioned in this paper, where the satellite is on a low inclination orbit that enhances the sampling over the intertropical belt.Abstract:
The Megha-Tropiques mission is operating since 12 October, 2011 and serves research and operational objectives related to the tropical water and energy cycle. The satellite is on a low inclination orbit that enhances the sampling over the intertropical belt. The original payloads were dedicated to the estimation of the radiation budget at the top of the atmosphere, the water vapor profiles and the instantaneous precipitation rate. The original suite of geophysical products that was developed permitted to demonstrate the proof of concept of the mission in the early part of its operation. Following an unfortunately expedited exploitation of the conically scanning multispectral radiometer (16 months), efforts have been geared to mitigate the loss by extending the use of the 183 GHz sounder towards the precipitation objectives. This induced some delays in the setting of the current set of products that are now being used for research investigations. Despites not being an operational meteorological satellite, the real time capability of the mission has shown its usefulness with a large and growing set of Numerical Weather Prediction centers assimilating the Megha-Tropiques data, in clear and total skies. After 7 years in space, the satellite and operating instruments are in excellent shape and sustain their very good initial performances. The mission has acquired a large and unique set of observations of the tropical water and energy cycle which is only at the beginning of its exploitation.read more

The Megha-Tropiques mission
TL;DR: The Megha-Tropiques satellite as mentioned in this paper is devoted to the study of the atmospheric water cycle in the tropics and its relation to the radiative budget, which is aimed to study both the energy and water budget of the intertropical band and the life cycle of the convective complexes in the Tropics.

The role of ocean‐atmosphere interactions in the CO2 climate problem
TL;DR: In this paper, the authors examined the role of ocean-atmosphere interactions in determining the surface warming to an increase in CO2 in a one-dimensional, 17-layer coupled ocean atmosphere model and found that the primary contribution to surface warming is from enhanced tropospheric IR emission, which is an order of magnitude greater than the direct CO2 radiative heating at the surface.

Controls of Global-Mean Precipitation Increases in Global Warming GCM Experiments
Graeme L. Stephens,Todd D. Ellis +1 more
TL;DR: In this article, the authors examined the control on global precipitation that are evident in the transient experiments conducted using coupled climate models collected for the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4), and the change in precipitation, water vapor, clouds, and radiative heating of the atmosphere evident in a 1% increase in carbon dioxide until doubled (1pctto2x) scenario is examined.

100 Years of Research on Mesoscale Convective Systems
TL;DR: When cumulonimbus clouds aggregate, developing into a single entity with precipitation covering a horizontal scale of hundreds of kilometers, they are called mesoscale convective systems as mentioned in this paper.
