All hardware except the antennas is new. There has been a complete rewrite of all processing routines as well as change in the netCDF format and variable names and attributes. Attempt has been made to preserve as much similarities as appropriate to the old WCR (WCR1) formatting. = After the 2nd of December flight the receiver associated with the up and down-slant beams became intermittently unsteady (fluctuations in the receiver noise/gain). Starting with the 14th of January flight the intermittent problem became more severe. Occasionally the noise floor (the gain) for the up and the down-slant beams changed by more than 2.5 dB. This leads to errors in the reflectivity factor. Expected maximum error is 4 dB, but typically, it appears to be within 2 dB. The reason for the problem is the low-noise amplifier servicing the receiver for the two above-mentioned beams. = The problem with one of the receivers described above is somewhat mitigated by splitting the affected data files (with usually small gaps in between to remove unreliable transitional behavior data) and adjusting the calibration constants. Each processed file uses one set of calibration coefficients. Data was not split when it was not practical. The times when the receiver changed its state, but the data was not split are noted in the Catalog above. Reflectivity factor: = Reflectivity absolute accuracy has not been established for WCR2 yet. Given the past experience no more than 2.5 dB uncertainty is expected. The precision for the full received power dynamic range of the radar is expected to be less than 1 dB due to the use of digital receivers, which do not exhibit significant non-linearities, drift, and receiver front end temperature dependence. The received power from the down-pointing antenna has been calibrated with a corner reflector. The up and down-slant channels are calibrated relative to the down-channel using weather targets. The receiver stability (excluding the problem for the up/down-slant beams receiver) is better than 0.5 dB/hour. = For all beams the reflectivity may be slightly elevated between the 20th and 80th range gates depending on the signal-to-noise ratio, SNR. The source has not been identified. The effect is negligible for stronger signals (higher SNR). = The transmitter leak to the first few range gates of the received signals is small (estimated to less than 0.3dB above the mean nosie) or not noticeable. = The recieved signal from the two down antennas can get saturated by weather targets stronger than about +22 dBZ in the first 200-300 m from the radar/aircraft. = Cross-antenna talk is possible. Strong down-aft antenna targets may leak to the up antenna return and strong down antenna targets may leak into the down-aft antenna return. The most frequent cross-talk contamination is from surface returns and it is apparent in the quick look images. = Reflecitvity is not corrected for attenuation due to absorption and scattering. It could be significant in the presence of liquid water and precipitation. Velocity: = Corrected Doppler velocity from the down-pointing beams may have bias of up to +- 1.5 m/s and uncertainty of up to +-1.0 m/s. Typical bias and uncertainty are less than +-0.5 m/s. It is our belief that the bias is mainly due to changes in the antennas pointing angles caused by flexing of the aircraft fuselage not represented in the IRS data. In addition the fuselage expands with altitude and this also changes slightly the antenna pointing directions. Errors in the IRS(navigation) data have an effect as well. = Corected Doppler velocity accuracy from the up-pointing antenna is not quantified with a known reference target. The analysis of appropriate weather targets suggests a maximum bias of ~1 m/s. = The errors in the beam pointing angles for the up and down beams as well as some other errors lead to possible discontinuity in the mean vertical Doppler velocity profile at the flight level. The discrepancy is generally less than 0.3 m/s and typically within 0.1 m/s. It is not established which beam is contributing more to this error. Given that the aircraft flexes/expands differently at the up antenna location and the 2 down antenna locations as well as the dependence of these distortions on the altitude and attitude of the aircraft there is no single optimal correction (optimal set of beam angles) for all conditions. = There seems to be a bias toward larger absolute velocity in the first range gate (105 m) of the beams. It is on the order of 0.1 m/s and diminishes with range. = The Doppler data occasionally exhibit folded velocity regions (mostly in the slanted beam return). We do not make an attempt to unfold due to difficulties of automating this process. Typically unfolding any specific data segment is not difficult. For help on this you may contact Samuel Haimov (haimov@uwyo.edu). * Known corrupted data not fixed in this revision: = Reflectivity data from flights after 13 January are affected by noise/gain fluctuations in the radar receiver associated with the up and down-slant beams (more details are given in the General notes above) ================================================================================
