O3 Retrieval Vectors

The version 5.0.xx retrieval algorithms use 11 unique wavelengths to generate 8 ozone retrieval vectors. 7 vector are in the Hartley Huggins region and 1 is in the Chappuis region. The large selection of retrieval vectors allows the algorithm to have good sensitivity across the entire alitude range.

Spectral Region Retrieval Vector
Hartley Huggins \(y_{j,k} = \ln\left( \frac{I(j,\lambda_{ref})}{I(j,\lambda_{abs})}\right)\)
Chappuis \(y_{j,k} = \ln\left(\frac{\sqrt{I(j,\lambda_{ref1})I(j,\lambda_{ref2})}}{I(j,\lambda_{abs})}\right)\)
