WebCoherent scatter radar provides a unique perspective of Joule heating by accessing both very small scales, but also providing spatial observations over mesoscales. However, investigations specifically focused on Joule heating from coherent radar observations are relatively limited compared to incoherent scatter radar. WebFirst, the difference between the coherent and noncoherent results decreases with increasing frequency for the same m for the m = 3 and 4 cases. The results for the m = 2 case show that the improvement factor is very similar at lower frequencies but performance diverges at higher frequencies.
