Field activities

Despite the snow, Biomet group members are active in the field:

Federico tested the impact of different integrated sampling times on bacterial DNA yields.

Next generation researchers

… active at our field site Neustift 😉

IMG_8309Everybody else being busy, Albin recently had to rely on his son’s help to do the necessary maintenance of the flux tower.

New papers in BG Special Issue and ACPD

With the frame of the recently completed Biogeosciences Special Issue „Towards the full GHG balance of the biosphere“  (http://www.biogeosciences.net/special_issue128.html), Georg contributed to the corresponding preface:

Merbold L., Wohlfahrt G., Butterbach-Bahl K., Pilegaard K., DelSontro T., Stoy P., Zona D. (2015) Preface: Towards a full greenhouse gas balance of the biosphere. Biogeosciences 12, 453-456, doi: 10.5194/bg-12-453-2015.

Another paper by Lukas and Georg has been published in the Special Issue already in December 2014:

Hörtnagl L., Wohlfahrt G. (2014) Methane and nitrous oxide exchange over a managed hay meadow. Biogeosciences 11, 7219-7236, doi: 10.5194/bg-11-7219-2014.

Another paper was published today in ACPD:

Wohlfahrt G., Amelynck C., Ammann C., Arneth A., Bamberger I., Goldstein A. H., Gu L., Guenther A., Hansel A., Heinesch B., Holst T., Hörtnagl L., Karl T., Laffineur Q., Neftel A., McKinney K., Munger J. W., Pallardy S. G., Schade G. W., Seco R., Schoon N. (2015) An ecosystem-scale perspective of the net land methanol flux: synthesis of micrometeorological flux measurements. Atmospheric Chemistry and Physics Discussions 15, 2577-2613, doi: 10.5194/acpd-15-2577-2015.

New paper and visitor

Mallick K., Jarvis A., Wohlfahrt G., Kiely G., Hirano T., Miyata A., Yamamoto S., Hoffmann L. (2015) Components of near-surface energy balance derived from satellite soundings – Part 1: Net available energy. Biogeosciences 12,433-451, doi: 10.5194/bg-12-433-2015.

 

Today Genki Katata, presently visiting scientist at KIT Garmisch-Partenkirchen, visited us to discuss about modelling grassland carbon and energy fluxes. The picture shows Genki (second on left) and part of the Biomet group enjoing lunch after an exhausting discussion about Bayesian calibration, parameter equifinality and other complicated stuff.

New paper

The paper reporting the outcomes of the first gaseous elemental mercury eddy covariance flux measurements near Reno/Nevada has finally come out in Environmental Science & Technology:

Pierce A., Moore C., Wohlfahrt G., Hörtnagl L., Kljun N., Obrist D. (2015) Eddy covariance flux measurements of gaseous elemental mercury using cavity ring-down spectroscopy. Environmental Science and Technology, doi: 10.1021/es505080z.
