TL;DR: The Modern-Era Retrospective Analysis for Research and Applications (MERRA) was undertaken by NASA's Global Modeling and Assimilation Office with two primary objectives: to place observations from NASA's Earth Observing System satellites into a climate context and to improve upon the hydrologic cycle represented in earlier generations of reanalyses as mentioned in this paper.

The Framework for Assimilating All-Sky GPM Microwave Imager Brightness Temperature Data in the NASA GEOS Data Assimilation System
TL;DR: Satellite radiance observations combine global coverage with high temporal and spatial resolution, and bring vital information to NWP analyses especially in areas where conventional data ar... as discussed by the authors, which is very relevant to our work.
All-Sky Microwave Imager Data Assimilation at NASA GMAO
TL;DR: In this paper, the authors provide an overview of the development of all-sky radiance assimilation in GEOS, including some performance metrics, and various projects underway at GMAO designed to enhance the all sky implementation will be introduced.
