# Aqua MODIS Electronic Crosstalk on SMWIR Bands 20 to 26

## TL;DR

This paper investigates electronic crosstalk in Aqua MODIS bands 20 to 26, identifying the source detectors and developing correction methods to improve image quality during lunar observations.

## Contribution

It identifies the source of electronic crosstalk in specific MODIS bands and proposes a correction method to reduce striping artifacts in L1B images.

## Key findings

- Crosstalk originates from detector 10 of the sending band.
- Crosstalk correction improves image quality by reducing striping artifacts.
- The source detector and immediate readout sequence are confirmed as key factors.

## Abstract

Aqua MODIS Moon images obtained with bands 20 to 26 (3.66 - 4.55 and 1.36 - 1.39 $\mu$m) during scheduled lunar events show evidence of electronic crosstalk contamination of the response of detector 1. In this work, we determined the sending bands for each receiving band. We found that the contaminating signal originates, in all cases, from the detector 10 of the corresponding sending band and that the signals registered by the receiving and sending detectors are always read out in immediate sequence. We used the lunar images to derive the crosstalk coefficients, which were then applied in the correction of electronic crosstalk striping artifacts present in L1B images, successfully restoring product quality.
