Correction of RS92 Mean Bias Error Relative to CFH, MWR, and ARM RH Probes

Above: Uncorrected RS92 difference from 3 reference sensors: CFH (altitude profiles, and P-dependence in 10 RH intervals); ARM MWR (ratio of PW); and certified ARM RH probes. Below: Corrected RS92 mean accuracy is ±2% for all RH conditions from the surface to several km above the tropopause based on comparisons with same sensors as above.
