We present revised observations made by the Mars Global Surveyor magnetometer of the crustal magnetic fields at Mars. We have implemented a new data analysis technique (enhanced analytic downward continuation) that brings out comparatively small scale regional features in the dataset. This increase in the spatial resolution allows for more detailed interpretations of the geophysical features such as the linear "stripes” of alternating polarity in the southern hemisphere. We discuss in detail the improvements that we have made to the analytic downward continuation technique. In particular, we discuss how the stability of upward continuation allows us to make iteratively better solutions of what the fields look like at lower observation altitudes (and hence higher spatial resolutions). Additionally, we explore how the usage of the observations made from both pre-mapping altitude ( 100 km) and mapping altitude ( 400 km) can further constrain the resulting solutions.
