Description

Begin doing some readings on how we can use MODTRAN to generate reference spectra of a feature we choose to apply to our smile algorithm

Begin by reading section 3.2 in the reference paper linked in the FINCH Smile Correction page

Notes for 3.2

3.2 High Resolution MODTRAN 4 data adaption

MODTRAN 4: atmospheric radiative transfer model

→ calculates the atmospheric transmittance, single and multiple scattered solar and thermal radiances

How to calculate the resampled spectra?

: Need to use the dot product between using spectral response function and MODTRAN high resolution data

Resampled spectra: low resolution spectra resulting from interaction between response function’s sensitivity and high resolution real world spectra

2.3: Simulation of resampled spectrum

• Vector Z: contains value of a Gaussian response function

• Vector Y: contains real world absorption feature

• Two vectors must have the same length → same number of vector elements
