| Subject: | GRW/WACR/M1 - Reprocessed: Reflectivity and Height Offsets |
| DataStreams: | grwwacrspeccmaskcopolM1.a0, grwwacrM1.b1 |
| Description: | The instrument vendor informed us of a range (height) offset of 13 m and provided updated reflectivity calibration. All values reported for 'Reflectivity' were approximately 3 dB too low. In addition, the Reflectivity in the first and fourth range gates (starting from the surface) needed to be further corrected by an additional 2.7 and -0.9 dB, respectively. The 'height' field values were 13.33 m too low. The data were reprocessed to correct these problems. The grwwacrM1.b1 data were reprocessed and archived in October 2010. The grwwacrspeccmaskcopolM1.a0 and grwwacrspeccmaskxpolM1.a0 data were reprocessed and archived in January 2012. |

| Subject: | GRW/WACR/M1 - Incorrect value for antenna_altitude global attribute |
| DataStreams: | grwwacrspeccmaskcopolM1.a0 |
| Description: | The global attribute antenna_altitude is incorrect. The correct value should be 3.8608 m. This is the height of the WACR antenna above the ground. The value is used, along with site altitude, in converting heights above MSL to range above the radar antenna. |
