MACC-III Input Data

Satellite data

Satellite observations are a crucial input to the MACC-III systems. MACC-III produces global services in near-real-time, in a delayed-mode configurations, and as a reanalysis.

Global near-real-time analysis and forecast system

The MACC-III global near-real-time (NRT) production system uses satellite data in its 4-dimensional variational (4D-Var) data assimilation system to constrain the initial atmospheric state that is used for the 5-day forecast. Apart from all the meteorological observations that form part of the ECMWF numerical weather prediction system, MACC-III uses additional observations on atmospheric composition. Three categories of observations are listed below. The assimilated observations are the observations that are currently used to constrain the model; the monitored observations are the observations that are part of the full system (NRT data acquisition, calculations of observation-model differences,...), but are not used yet to constrain the model; planned observations are observations that are being considered to be implemented in the MACC-III system.

Global delayed-mode analysis and forecast system

The MACC-III delayed-mode (DM) production system uses satellite data in its 4-dimensional variational (4D-Var) data assimilation system to constrain the initial atmospheric state that is used for the 4-day forecast. Apart from all the meteorological observations that form part of the ECMWF numerical weather prediction system, MACC-III uses additional observations on atmospheric composition. Three categories of observations are listed below. The assimilated observations are the observations that are currently used to constrain the model; the monitored observations are the observations that are part of the full system (DM data acquisition, calculations of observation-model differences,...), but are not used yet to constrain the model; planned observations are observations that are being considered to be implemented in the MACC-III system.

Global reanalysis

The MACC-II reanalysis (REA) production system uses satellite data in its 4-dimensional variational (4D-Var) data assimilation system to constrain the atmospheric state every 6 hours. Apart from all the meteorological observations that form part of the ECMWF numerical weather prediction system, MACC-II uses additional observations on atmospheric composition. Only one category of observations is listed below, the assimilated observations are the observations that are used to constrain the model.
