11.18.2014 CO2 Global Transport Simulation from GEOS-5 Nature Run

A NASA press release shows a GMAO animation of the transport of carbon dioxide from May 2005 to June 2007, as simulated using the GEOS-5 model. The Nature Run simulation models this process on a 7 km grid. See NASA Press Release:

10.30.2014 Quantifying the observability of CO2 flux uncertainty in atmospheric CO2 records using products from NASA's Carbon Monitoring Flux Pilot Project

Carbon dioxide (CO2) is an important greenhouse gas, yet much uncertainty surrounds the processes controlling its flux from land and ocean to atmosphere. NASA’s GEOS-5 model was used to transport different flux estimates through the atmosphere to assess when uncertainties related to flux estimates were large enough to distinguish from weather-induced natural variations.

9.19.2014 Sensitivity of Tropical Cyclones to Parameterized Convection in the GEOS-5 Model

This study demonstrates that realistic Tropical Cyclone activity can be simulated in GCMs with a resolution of about 25km and that modifications to the convective parametrization can lead to further improvements in the realism of the TCs. Read more.

09.11.2014 Interannual Variation in Phytoplankton Primary Production at a Global Scale

The contributions of four phytoplankton groups to the total primary production are computed using the GMAO’s "NASA Ocean Biology Model." The work isolates the effects of climate variability on group-specific primary production using global and regional climate indices. Read more.

02.14.2014 High-resolution GEOS-5 simulations of stratospheric ozone intrusions

A 25-km resolution version of GEOS-5 has been used with a comprehensive stratosphere-troposphere chemistry module to test the feasibility of detecting the impacts of stratospheric ozone intrusions on surface air quality. Read more.

01.10.2014 GEOS iODAS: Ocean Data Portal

The GMAO ocean data assimilation (GEOS iODAS) output is now available online. Output includes a one-degree analysis from 1960-2009, that is used to initialize the GMAO decadal forecasts, and a half-degree analysis, beginning in 1993, that assimilates altimeter data. The half-degree analysis is included in the ensemble of analyses used to initialize the GMAO seasonal forecasts from 1982 onwards.
