Abstract. The Sentinel-5 Precursor (S5P) mission with the TROPOspheric Monitoring Instrument (TROPOMI) on board has been measuring solar radiation backscattered by Earth's atmosphere and surface since its launch 13 October 2017. In this paper, we present for first time S5P operational methane (CH4) carbon monoxide (CO) products' validation results covering a period of about 3 years using global Total Carbon Column Observing Network (TCCON) Infrared Working Group Detection Atmospheric...
Abstract. The Total Carbon Column Observing Network (TCCON) measures column-average mole fractions of several greenhouse gases (GHGs) beginning in 2004 from over 30 current or past measurement sites around the world, using solar absorption spectroscopy near infrared region. TCCON GHG data have been used extensively for multiple purposes, including studies carbon cycle and anthropogenic emissions as well to validate improve observations made spacebased sensors. Here, we describe an update...

Abstract. Optimal estimation retrievals of trace gas total columns require prior vertical profiles the gases retrieved to drive forward model and ensure retrieval problem is mathematically well posed. For well-mixed gases, it possible derive accurate using an algorithm that accounts for general patterns atmospheric transport coupled with measured time series in questions. Here we describe used generate GGG2020, a new version GGG analyze spectra from solar-viewing Fourier transform...
Abstract. We show new results from an updated version of the Fast atmOspheric traCe gAs retrievaL (FOCAL) retrieval method applied to measurements Greenhouse gases Observing SATellite (GOSAT) and its successor GOSAT-2. FOCAL was originally developed for estimating total column carbon dioxide mixing ratio (XCO2) spectral made by Orbiting Carbon Observatory-2 (OCO-2). However, depending on available windows, also successfully retrieves amounts other atmospheric species their uncertainties...
Observations of key gaseous trace pollutants, namely NO, NOy, CO, SO2 and O3, performed at several curb, residential, industrial, background free-troposphere sites were analyzed to assess the temporal spatial variability pollution in Cyprus. Notably, analysis utilized one longest datasets 17 years measurements (2003-2019) East Mediterranean Middle (EMME). This region is considered a regional hotspot ozone aerosol pollution. A trend revealed that stations, statistically significant decrease...

Methane (CH4) carbon monoxide (CO) data a spatial resolution (initially 7 x km2, upgraded to 5.5 km2 6th of August 2019) have retrieved from shortwave infrared (SWIR) near-infrared (NIR) measurements end November 2017 made available experts for early validation...
At the crossroads of Europe, Africa, and Asia, island Cyprus receives long-range regional pollution from various anthropogenic natural sources. To assess variability amounts greenhouse gases (GHG) in region, we have set up, 2019, a new Total Carbon Column Observing Network (TCCON) site, TCCON Nicosia, at The Institute. Herewith, present first time series columnar main GHGs region (Xgas; X stands for total column average dry-air mole fractions), namely carbon dioxide (XCO2), methane (XCH4),...
Abstract. Recently, the Fast atmOspheric traCe gAs retrievaL (FOCAL) algorithm has been applied to measurements of Greenhouse gases Observing SATellite (GOSAT) and its successor GOSAT-2. FOCAL originally developed for Orbiting Carbon Observatory-2 (OCO-2) retrievals with focus on derivation carbon dioxide (XCO2). However, depending available spectral windows, also successfully retrieves total column amounts other atmospheric species. Here, we show new results from updated GOSAT GOSAT-2...
