To jest analiza, nie prognoza, choć w przypadku GMAO (a konkretnie GEOS-5) jest to już prognoza, bo obejmuje czas t+00:30
Zresztą to eksperymentalny model:
"A unique aspect of the project was the use of new satellite data sets by scientists at the Global Modeling and Assimilation Office (GMAO). The GEOS-5 atmospheric model is a weather-and-climate capable model which has been integrated with the NCEP/GMAO GSI to produce a new atmospheric data assimilation system (DAS), the GEOS-5 DAS. The global model forecasts for MAP '06 were at 1/4 degree with 72 vertical levels. Initial conditions during the early phase of the project were acquired from the NCEP Global Forecast System (GFS). Analyses from the GEOS-5 DAS were available for model initialization in late August. During the course of the project, depending on the availability of computational resources, tests of the data assimilation system were conducted at 1/4 degree resolution. Five-day global model forecasts were conducted up to twice per day. A prototype version of GEOS-5 that incorporated the direct effect of aerosols on radiation was incorporated into the project later in the summer to study the impact of sub-Saharan dust on tropical cyclone development in the eastern Atlantic."
I nie taki nowy - powyższe słowa były pisane odnośnie projektu MAP-06, który istniał w 2006 roku.
