## TL;DR

This paper demonstrates the retrieval of atmospheric CO2 concentrations from Argus 1000 satellite spectral data using the GENSPECT line-by-line radiative transfer model, revealing a 30% increase over British Columbia.

## Contribution

It introduces a novel application of the GENSPECT model for CO2 retrieval from Argus 1000 data in the near-infrared spectrum.

## Key findings

- CO2 was successfully retrieved from Argus 1000 data.

- Validated the effectiveness of line-by-line radiative transfer modeling.

## Abstract

The micro-spectrometer Argus 1000 being in space continuously monitors the sources and sinks of the trace gases. It is commonly believed that among other gases $\text{CO}_\text{2}$ is the major contributor causing the greenhouse effect. Argus 1000 along its orbit gathers the valuable spectral data that can be analyzed and retrieved. In this paper we present the retrieval of $\text{CO}_\text{2}$ gas in the near infrared window $1580$ to $1620$ nm by using line-by-line code GENSPECT. The retrieved Argus 1000 space data taken over British Columbia on May 31, 2010 indicates an enhancement of $\text{CO}_\text{2}$ by about $30\%$.
