Hi, I want to compute corrected reflectivity (Z\_Corr) from the measured reflectivity (Z\_m) with summation of the Path Integrated Attenuation (PIA). Here is the equation; Z\_Corr = PIA + Z\_m. The dataset is an RHI netCDF file format. The original file contains the measured reflectivity (Z\_m), while the processed RHI file in netCDF format has the specific attenuation (dB/km) and corrected reflectivity (Zcorr) products. I want to compare the computed corrected reflectivity (Z\_Corr) and the processed corrected reflectivity (Zcorr).
