Optimal estimation retrievals of trace gas total columns require prior vertical profiles of the
gases retrieved to drive the forward model and ensure the retrieval problem is …

Adapting to climate change as a consequence of increasing greenhouse gas (GHG)
emissions is of paramount importance in the near future. Therefore, recognition of spatial …

Abstract CO 2 concentration (XCO 2) shows the spatial and temporal variation in Iran. The
major purpose of this investigation is the assessment of the spatial distribution of carbon …

We describe a method for removing systematic biases of column-averaged dry air mole
fractions of CO 2 (XCO 2) and CH 4 (XCH 4) derived from short-wavelength infrared (SWIR) …

The thermal And near infrared sensor for carbon observations Fourier transform
spectrometer (TANSO-FTS) on board the Greenhouse Gases Observing Satellite (GOSAT) …

On-chip spectrometers with high compactness and portability enable new applications in
scientific research and industrial development. Fourier transform (FT) spectrometers have …

Methane (CH 4) is the simplest hydrocarbon in the atmosphere and is the second most
important greenhouse gas (GHG) after carbon dioxide (CO 2) whose concentration is …

Global warming and climate change have been identified as the most important challenges
of the 21st century. G reenhouse G ases O bservation S atellite (GOSAT) measures the …

Atmospheric methane (CH4) is an important greenhouse gas that can reflect variations of
CH4 emissions and sinks. This study aimed to detect spatial and temporal variations of …

Understanding the atmospheric distribution of water (H 2 O) is crucial for global warming
studies and climate change mitigation. In this context, reliable satellite data are extremely …
