## Relating Mars Observations with Earth ObservationsMARIE/GOES Data ComparisonA month-by-month comparison of MARIE dose-rate data with GOES integral particle flux data

- MARIE data are derived from the count-rate on the MARIE instrument on the Odyssey Spacecraft in orbit around MarsGOES data are derived from the Space Environment Monitor in geostationary Earth orbit (archived by the National Geophysical Data Center)A side-bar shows the relative positions of Earth and Mars at the beginning, middle, and end of each month
