 \paragraph{Upper Level Moisture}
 The fizhi package uses climatological water vapor data above 100 mb from the Stratospheric Aerosol and Gas 
 Experiment (SAGE) as input into the model's radiation packages.  The SAGE data is archived
-as monthly zonal means at 5$^\circ$ latitudinal resolution.  The data is interpolated to the
+as monthly zonal means at $5^\circ$ latitudinal resolution.  The data is interpolated to the
 model's grid location and current time, and blended with the GCM's moisture data.  Below 300 mb,
 the model's moisture data is used.  Above 100 mb, the SAGE data is used.  Between 100 and 300 mb,
 a linear interpolation (in pressure) is performed using the data from SAGE and the GCM.
