Z-Based Intervening Attenuation

You can configure the coefficients used for the intervening attenuation correction.

When enabled, the corrected reflectivity Zc is computed from Z using the following equation:

Where C is the constant above, and E is the exponent. All values of Z are clipped at the maximum Z before the calculation, and the total correction is clipped at the maximum cumulative value.

We have default values for C and X band radars. We recommend no correction be used for an S-band radar.

These numbers are used in both the ongest process if turned on in the task configuration menu, and at reingest time when data arrives over the network, if the Atten correction in Reingest button is pressed.
