Predicted and observed magnetic signatures of Martian (de)magnetized impact craters

Abstract : ► Forward approach allows to predict the magnetic signature of impact craters. ► MGS magnetic data are used to estimate true magnetic field above craters. ► Craters as small as 200-km have significant signatures at 400-km altitude. ► These could be used for timing the dynamo cessation This highlights the need for complementary measurements
