Investigating the impact of Covid-19 on the atmospheric 14C trend and fossil carbon load at urban and background sites in Hungary
The study analyses in situ CO 2 mole fraction, 14 CO 2 , and fossil based excess CO 2 mole fraction (C foss ) data at Hegyhátsál (HUN) rural monitoring station (Central Europe) supplemented by passive monitoring of 14 C content of tree-rings. Through the observed period (2014–2020) we focused on revealing trends in atmospheric CO 2 and 14 C levels, particularly during the year of the first COVID lockdown, in comparison to the preceding five years…
Temporal Variation of Atmospheric Fossil and Modern CO 2 Excess at a Central European Rural Tower Station between 2008 and 2014
In 2008, the atmospheric CO 2 measurements at the Hegyhátsál rural tower station were extended further by 14 CO 2 air sampling from two elevations (115 and 10 m a.g.l.), in cooperation with HEKAL (ICER). Since then, a complete six-year-long (2008–2014) dataset of atmospheric CO 2 , Δ 14 C, fossil, and modern CO 2 excess (relative to Jungfraujoch) has been assembled and evaluated. Based on our results, the annual mean CO 2 mole fraction rose at bo…
One-Year-Long Continuous and Synchronous Data Set of Fossil Carbon in Atmospheric PM 2.5 and Carbon Dioxide in Debrecen, Hungary
Radiocarbon investigation of atmospheric PM 2.5 aerosol synchronized with 14 CO 2 observations began in Debrecen in the winter of 2010. The aim of the study was to determine the contemporary and fossil carbon fractions in the aerosol and to set them against the fossil CO 2 excess data referring to the same period. The mass of the collected PM 2.5 mode on prebaked quartz filters was determined gravimetrically, while its total carbon mass was calcu…
Climate control of terrestrial carbon exchange across biomes and continents
Understanding the relationships between climate and carbon exchange by terrestrial ecosystems \nis critical to predict future levels of atmospheric carbon dioxide because of the potential \naccelerating effects of positive climate–carbon cycle feedbacks. However, directly observed \nrelationships between climate and terrestrial CO2 exchange with the atmosphere across biomes \nand continents are lacking. Here we present data describing the relatio…
