Description
GREEN is a global model that combines local models developed at ONERA (IGE-2006, OPAL, OZONE, Slot,…) and AE/P8 for mission duration longer than 1 year. This model is solar-cycle dependent and can provide both mean and upper envelop fluxes, accounting for the dynamics between successive solar cycles. The objective of GREEN-NG, the new version of GREEN, is to replace the combination of local models and AE/P8 with reanalysis databases (see abstract from Nour Dahmen, ONERA). Like its predecessor, GREEN-NG will depend on the year within the solar cycle and will remain valid for missions exceeding one year in duration. This model, currently under development, leverages physics-based long-term reconstruction of the dynamics of the radiation belts to build an improved global model while preserving the well established quality of the different local models. GREEN-NG is currently under development with funding from CNES and ONERA.
