Subject:	NSA/WSACR/C1 - Mean Doppler Velocity sign reversed
DataStreams:	nsawsacrawrhiC1.b1, nsawsacrblrhiC1.b1, nsawsacrcwrhiC1.b1, nsawsacrhsrhiC1.b1, nsawsacrppiC1.b1, nsawsacrrhiC1.b1, nsawsacrspeccmaskcopolC1.a0, nsawsacrspeccmaskxpolC1.a0, nsawsacrvptC1.b1
Description:	The signs of the mean_doppler_velocity field values are incorrect. The ARM convention for this field is that positive velocities indicate motion away from the radar. However, the velocity data in these files have their signs reversed, so that motion TOWARD the radar has a positive sign.

Description:	When comparing against the XSAPR, there is a noticeable 180 degree offset in the returns. This stems from problems with the pedestal.

Subject:	NSA/KASACR/C1 - Data collection problem
DataStreams:	nsakasacrawrhiC1.b1, nsakasacrblrhiC1.b1, nsakasacrcwrhiC1.b1, nsakasacrhsrhiC1.b1, nsakasacrppiC1.b1, nsakasacrrhiC1.b1, nsakasacrspeccmaskcopolC1.a0, nsakasacrspeccmaskxpolC1.a0, nsakasacrvptC1.b1
Description:	1. The sign of Doppler velocity of Ka/WSACR has been changed. The sign of Doppler velocity of WSACR was inconsistent with KAZR and KaSACR from December 14, 2012 to January 15, 2013. Before December 14, 2012, Doppler velocity signs from both W and Ka SACRs were inconsistent with KAZR. After February 1, 2013, the signs from SACRs are consistent with KAZR. 2. Ka/WSACR spectra have significant leakage, but something is clearly wrong with the KaSACR (see attached file). The WSACR leakage occurs only at higher SNR, but that when it occurs the first side lobe is only ~30 dB down, much less that the ~50 dB for the KAZR. 3. We could not find Doppler spectra data from Ka and W SACRs for the same time periods even though moments files for the vertical pointing scans for both Ka and W SACRs exist. There are synchronized signals in Doppler spectram in vertical potinting data from Ka/WSACR.
