What is EMMREM?

EMMREM is a numerical module that integrates numerous sub-modules describing radiation transport, and planetary interactions to predict radiation exposure. EMMREM behaves as an effective "Green's Function"; for broad use by researchers and modelers to predict radiation exposure by integrating over almost any incident particle distribution from interplanetary space.

Mission Statement

The central objective of the Earth-Moon-Mars Radiation Environment Module (EMMREM), is to develop and validate a numerical module for completely characterizing time-dependent radiation exposure in the Earth-Moon-Mars and Interplanetary space environments. EMMREM provides the ability to predict radiation exposure anywhere on the surface of Earth, the Moon, or Mars, in the atmosphere of Earth, and in the space between Earth and Mars given the energy spectrum, angular distribution, and elemental composition of particle radiation in the solar wind. EMMREM is designed with straightforward, and well-tested interfaces for broad use by researchers and modelers to predict radiation exposure. For more about relevant radiation hazards, click here.

What will this website provide?

The web-page provides links for users to choose specific simulated events and time-series, observed events and time-series, or user-specified input for the energy and angular distributions incident from interplanetary space. Users specify: (1) LEO, Moon, and Mars scenarios including altitudes and/or orbits; (2) shielding materials, optional spacecraft, habitat,spacesuit, human CAF/CAM models, and optional surface (albedo) effects. Module output are retrievable as time-series and time-averages. These may be compared to observed events(LRO/CRaTER, MSL/RAD, MARIE, ISS, Space Shuttle) or accelerator measurement case studies.
