“…30 mmol m −2 h −1 during the summer and autumn months and minimum values of less than 10 mmol m −2 h −1 during the winter and early spring. The range of summer values of CO 2 flux is in good agreement with direct soil CO 2 flux measurements in Krakow from 2009 to 2013, using the static chamber method (Jasek et al 2014), while the winter results are significantly higher compared to chamber measurements. This difference can be explained by different fluxes in these two methods.…”

Anthropogenic emissions of carbon dioxide (CO 2) and methane (CH 4) in the atmosphere constitute an important component of the related carbon budget. The main source of anthropogenic CO 2 is burning of fossil fuels, especially in densely populated areas. Similar emissions of CH 4 are associated with the agricultural sector, coal mining, and other human activities, such as waste management and storage and natural gas networks supplying methane to large urban, industrial centers. We discuss several methods aimed at characterizing and quantifying atmospheric loads and fluxes of CO 2 and CH 4 in Krakow, the second largest city in Poland. The methods are based on atmospheric observations of mixing ratios as well as isotopic composition of the investigated gases. Atmospheric mixing ratios of CO 2 and CH 4 were measured using gas chromatography (GC) and cavity ring-down spectroscopy (CRDS). The isotopic composition of CO 2 and CH 4 was analyzed using isotope ratio mass spectrometry (IRMS), accelerator mass spectrometry (AMS), and CRDS techniques. These data, combined with auxiliary information characterizing the intensity of vertical mixing in the lower atmosphere (height of the nocturnal boundary layer [NBL] and atmospheric 222 Rn concentration), were further used to quantify emission rates of CO 2 and CH 4 in the urban atmosphere of Krakow. These methods provide an efficient way of quantifying surface emissions of major greenhouse gases originating from distributed sources, thus complementing the widely used bottom-up methodology based on emission statistics.

“…The updated SRBD-V5 will further support the analysis of how different manipulations affect R S . In the past decades, many field experiments have been conducted to study different questions, for example, how soil carbon responds to global climatic warming and changes in precipitation patterns (Vicca et al, 2014) or how human activities (forest management, agriculture cultivation, and pollution) affect terrestrial carbon cycling and soil carbon stock (Carrillo et al, 2014;Jasek et al, 2014). However, inconsistent results from different experiments have generated debate regarding the effects of environmental factors and manipulations in R S .…”

Abstract. Field-measured soil respiration (RS, the soil-to-atmosphere CO2 flux) observations were compiled into a global soil respiration database (SRDB) a decade ago, a resource that has been widely used by the biogeochemistry community to advance our understanding of RS dynamics. Novel carbon cycle science questions require updated and augmented global information with better interoperability among datasets. Here, we restructured and updated the global RS database to version SRDB-V5. The updated version has all previous fields revised for consistency and simplicity, and it has several new fields to include ancillary information (e.g., RS measurement time, collar insertion depth, collar area). The new SRDB-V5 includes published papers through 2017 (800 independent studies), where total observations increased from 6633 in SRDB-V4 to 10 366 in SRDB-V5. The SRDB-V5 features more RS data published in the Russian and Chinese scientific literature and has an improved global spatio-temporal coverage and improved global climate space representation. We also restructured the database so that it has stronger interoperability with other datasets related to carbon cycle science. For instance, linking SRDB-V5 with an hourly timescale global soil respiration database (HGRsD) and a community database for continuous soil respiration (COSORE) enables researchers to explore new questions. The updated SRDB-V5 aims to be a data framework for the scientific community to share seasonal to annual field RS measurements, and it provides opportunities for the biogeochemistry community to better understand the spatial and temporal variability in RS, its components, and the overall carbon cycle. The database can be downloaded at https://github.com/bpbond/srdb and will be made available in the Oak Ridge National Laboratory's Distributed Active Archive Center (ORNL DAAC). All data and code to reproduce the results in this study can be found at https://doi.org/10.5281/zenodo.3876443 (Jian and Bond-Lamberty, 2020).
