Volatile Organic Compound emissions from soil: using Proton-Transfer-Reaction Time-of-Flight Mass Spectrometry (PTR-TOF-MS) for the real time observation of microbial processes

Autor: Veres, P. R., Behrendt, T., Klapthor, A., Meixner, F. X., Williams, J.

In this study we report on the emissions of volatile organic compounds (VOC) and nitric oxide (NO) from two contrasting soils (equatorial rainforest and arid cotton field) analyzed in a laboratory based dynamic chamber system. The effect of soil mois

Use of laboratory and remote sensing techniques to estimate vegetation patch scale emissions of nitric oxide from an arid Kalahari savanna

Autor: Feig, G. T., Mamtimin, B., Meixner, F. X.

The biogenic emission of nitric oxide (NO) from the soil has an important impact on a number of environmental issues, such as the production of tropospheric ozone, the cycle of the hydroxyl radical (OH) and the production of NO. In this study we coll

The contribution of soil biogenic NO eand HONO emissions from a managed hyperarid ecosystem to the regional NOx emissions during growing season

Autor: Mamtimin, B., Badawy, M., Behrendt, T., Meixner, F., Wagner, T.

Publikováno v: Atmospheric Chemistry and Physics

A study was carried out to understand the contributions of soil biogenic NO emissions from managed (fertilized and irrigated) hyper-arid ecosystem in NW-China to the regional NO2 emissions during growing season. Soil biogenic NO emissions were 5 quan

The dynamic chamber method: trace gas exchange fluxes (NO, NO2, O3) between plants and the atmosphere in the laboratory and in the field

Autor: Breuninger, C., Oswald, R., Kesselmeier, J., Meixner, F. X.

Publikováno v: Atmospheric Measurement Techniques, Vol 5, Iss 5, Pp 955-989 (2012)

We describe a dynamic chamber system to determine reactive trace gas exchange fluxes between plants and the atmosphere under laboratory and, with small modifications, also under field conditions. The system allows measurements of the flux density of

Acute aerobic exercise and attentional focus influence the self-positivity bias in emotional evaluation. Evidence from an experimental study

Autor: Meixner Friedrich, Herbert Cornelia

Publikováno v: Open Psychology, Vol 4, Iss 1, Pp 187-204 (2022)

The influence of aerobic exercise, as a possibly mood-enhancing experience, was investigated for its effect on emotional evaluation of self- vs. other-related emotional (e.g., my/his joy) or neutral (e.g., my/his notes) stimuli. N=30 participants (he

Laboratory measurements of nitric oxide release from forest soil with a thick organic layer under different understory types

Autor: Bargsten, A., Falge, E., Pritsch, K., Huwe, B., Meixner, F. X.

Publikováno v: Biogeosciences, Vol 7, Iss 5, Pp 1425-1441 (2010)
Biogeosciences 7, 1425-1441 (2010)

Nitric oxide (NO) plays an important role in the photochemistry of the troposphere. NO from soil contributes up to 40% to the global budget of atmospheric NO. Soil NO emissions are primarily caused by biological activity (nitrification and denitrific

Aerodynamic gradient measurements of the NH3-HNO3-NH4NO3 triad using a wet chemical instrument: an analysis of precision requirements and flux errors

Autor: Wolff, V., Trebs, I., Ammann, C., Meixner, F. X.

Publikováno v: Atmospheric Measurement Techniques, Vol 3, Iss 1, Pp 187-208 (2010)

The aerodynamic gradient method is widely used for flux measurements of ammonia, nitric acid, particulate ammonium nitrate (the NH3-HNO3-NH4NO3 triad) and other water-soluble reactive trace compounds. The surface exchange flux is derived from a measu
