Subject:	SGP/XSAPR/I4 - Data Quality Impacted
DataStreams:	sgpxsaprppiI4.00, sgpxsaprvadI4.00, sgpxsaprunkI4.00, sgpxsaprhsrhiI4.00, sgpxsaprvptI4.00
Description:	The XSAPR came back up for a short period of time. Radar not properly calibrated and suffered from other problems noted below. Differential reflectivity values all greater than 4 dB Correlation Coefficient values and all below acceptable levels (most below 0.8). PhiDp values noisy and do not appear to increase with range Specific differential reflectivity is incorrectly calculated. Elevated background noise in the reflectivity.
Suggestions:	Use data with Caution
