In support of the first Tropospheric Ozone Assessment Report (TOAR) a relational database global surface ozone observations has been developed and populated with hourly measurement data enhanced metadata. A comprehensive suite products including standard statistics, health vegetation impact metrics, trend information, are made available through common portal web interface. These form basis TOAR analyses focusing on human health, vegetation, climate relevant issues, which part this special...
Abstract We present an estimate of net ecosystem exchange (NEE) CO 2 in Europe for the years 2001–2007. It is derived with a data assimilation that uses large set atmospheric mole fraction observations (∼70 000) to guide relatively simple descriptions terrestrial and oceanic exchange, while fossil fuel fire emissions are prescribed. Weekly sources sinks optimized (i.e., flux inversion) 18 ecosystems across which prescribed climate, weather, surface characteristics introduce finer scale...
Abstract. We have constructed an atmospheric inversion framework based on TM5-4DVAR to jointly assimilate measurements of methane and δ13C in order estimate source-specific emissions. Here we present global emission estimates from this for the period 1999–2016. a newly constructed, multi-agency database CH4 measurements. find that traditional CH4-only inversions are unlikely emissions consistent with data, assimilating data is necessary derive both Our attributes ca. 85 % post-2007 growth...
During the summer of 2018, a widespread drought developed over Northern and Central Europe. The increase in temperature reduction soil moisture have influenced carbon dioxide (CO2) exchange between atmosphere terrestrial ecosystems various ways, such as photosynthesis, changes ecosystem respiration, or allowing more frequent fires. In this study, we characterize resulting perturbation atmospheric CO2 seasonal cycles. 2018 has good coverage European regions affected by drought, investigation...
Abstract. We present a global distribution of surface methane (CH4) emission estimates for 2000–2012 derived using the CarbonTracker Europe-CH4 (CTE-CH4) data assimilation system. In CTE-CH4, anthropogenic and biospheric CH4 emissions are simultaneously estimated based on constraints atmospheric in situ observations. The system was configured to either estimate only or sources per region, both categories simultaneously. latter increased number optimizable parameters from 62 78. addition,...
Abstract. The Bayesian framework of CO2 flux inversions permits estimates the retrieved uncertainties. Here, reliability these theoretical is studied through a comparison against misfits between inverted fluxes and independent measurements Net Ecosystem Exchange (NEE) made by eddy covariance technique at local (few hectares) scale. Regional 0.5° resolution are applied for western European domain where ~ 50 sites operated. These conducted period 2002–2007. They use mesoscale atmospheric...
Abstract. The concentration of ozone at the Earth's surface is measured many locations across globe for purposes air quality monitoring and atmospheric chemistry research. We have brought together all publicly available observations from online databases modern era to build a consistent data set evaluation chemical transport chemistry-climate (Earth System) models projects such as Chemistry-Climate Model Initiative Aer-Chem-MIP. From total approximately 6600 sites 500 million hourly...
The atmospheric background CO2 concentration is a key quantity for the analysis and evaluation of ongoing climate change. Long-term observations have been carried out at high Plateau Rosa mountain station, in north-western Alps since 1989. complete time series covers thirty years, it suitable climatological analysis. continuous measurements, collected 1993, were selected, by means BaDS (Background Data Selection) filter, to obtain hourly data. monthly data was analysed order individuate...
The atmospheric monitoring station at Plateau Rosa, situated in the Central European Alps and part of ICOS (Integrated Carbon Observation System) framework since 2021, is measuring methane mole fractions 2018 with a cavity ring down spectrometer (Picarro G2301). Concentration measurements this site, 3480 meter AMSL, are particularly valuable for tracking background global trend methane, but also impacted by various source areas Europe.In study, we analyzed continuous record station,...
Northern Italy is one of the most polluted and densely populated areas in Europe. The diversity land use Po basin makes this region an important contributor to greenhouse gas emissions from different sources. Medium large cities, as well industrialised areas, contribute significantly industrial processes, combustion, waste management natural distribution.As part H2020 RI-URBANS project (https://riurbans.eu/) synergy with PNRR “ITINERIS” Project, a pilot study has been...
Abstract. This work presents the new model called CRHyME (Climatic Rainfall Hydrogeological Modelling Experiment), a tool for geo-hydrological hazard evaluation. is physically based and spatially distributed written in Python language that represents an extension of classic hydrological models working at basin scale. CRHyME's main focus consists simulating rainfall-induced instabilities such as shallow landslides, debris flows, catchment erosion sediment transport into river. These phenomena...
We describe and implement a data selection algorithm aimed at identifying background atmospheric CO2 observations from in situ continuous measurements. Several criteria for detecting the have been developed are currently used: main objective of this work was to define common methodology extract signal minimizing heterogeneities due use different algorithms. The used study, (BaDS, Background Data Selection) tested optimized using (from 2014 2018) four Italian stations characterized by...
The Plateau Rosa Alpine station (Italy) has collected atmospheric concentrations of carbon dioxide since 1989. If the complete set hourly data is observed, two distinct and exceptional very high concentration events are evident for February 2004. Similar almost contemporary peaks were registered at European high–altitude stations Zugspitze–Schneefernerhaus Sonnblick in Alps, Mt. Cimone Northern Apennines. A regional meteorological model (the Weather Research Forecast) was applied over a...
Abstract. We investigate the sensitivity of future spaceborne lidar measurements to changes in surface methane emissions. use observations from nine European ground stations and a Lagrangian transport model infer emissions for 2010. Our inversion shows strongest Netherlands, coal mines Upper Silesia, Poland, wetlands southern Finland. The simulated concentrations capture at least half daily variability observations, suggesting that is correctly simulating regional pathways over Europe. With...
Abstract. Gobal methane emissions were estimated for 2000–2012 using the CarbonTracker Europe-CH4 (CTE-CH4) data assimilation system. In CTE-CH4, anthropogenic and biosphere of CH4 are simultaneously constrained by global atmospheric in-situ mole fraction observations. We use three configurations developed in Tsuruta et al. (2016) to assess sensitivity flux estimates (a) number unknown scaling factors be optimized which turn depends on choice underlying land-ecosystem map, (b)...
The Mediterranean basin is considered a global hot-spot region for climate change and air quality, especially concerning summer-time ozone (O3). Previous investigations indicated that the preferred stratosphere-to-troposphere exchange (STE) deep stratospheric intrusion (SI) events. Lagrangian tool STEFLUX, based on STE climatology uses ERA Interim data, was hereby used to diagnose occurrence of SI events in four mountain regions over Italian peninsula, spanning from Alpine southern...

Abstract A methodology for estimating secular daily minimum, mean and maximum (T n , T m x ) temperature records any urbanised point of a 30-arc-second-resolution grid covering Italy is presented. It based on the superimposition 1961–1990 climatologies departures from them (anomalies). The anomalies are obtained by applying inverse distance weighting to 143 Italian high-quality records, whereas larger dataset application local weighted linear regression versus elevation. grid-point then used...
