Grassland greening on the Mongolian Plateau despite higher grazing intensity
; Sun, Zhanli; Ren, Yanjun; Schierhorn, Florian; (Land Degradation & Development, 2020-10-01)
Changes in land management and climate alter vegetation dynamics, but the determinants of vegetation changes often remain elusive, especially in global drylands. Here we assess the determinants of grassland greenness on ... -

Gravity and magnetic investigations along the Peruvian continental margin
(Univ. Hamburg, 2002)This work presents the first three-dimensional gravity and magnetic investigation along the convergent Peruvian margin. Three-dimensional magnetic modelling is still a relatively untried and challenging technique. The ... -
Gravity Field Modeling Using Tesseroids with Variable Density in the Vertical Direction
; ; (Surveys in Geophysics, 2020-03-26)
We present an accurate method for the calculation of gravitational potential (GP), vector (GV), and gradient tensor (GGT) of a tesseroid, considering a density model in the form of a polynomial up to cubic order along the ... -
Gravity field modelling for the Hannover 10 m atom interferometer

Greenhouse gas emissions from soils—A review
Oertel, Cornelius;; Zurba, Kamal; Zimmermann, Frank; Erasmi, Stefan (Chemie der Erde - Geochemistry, 2016)
Soils act as sources and sinks for greenhouse gases (GHG) such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Since both storage and emission capacities may be large, precise quantifications are needed ... -
Greenhouse Gas Mitigation Potential of Alternate Wetting and Drying for Rice Production at National Scale—A Modeling Case Study for the Philippines
; ; ; ; ; ; ; (Journal of Geophysical Research: Biogeosciences, 2022-05-09)
Worldwide, rice production contributes about 10% of total greenhouse gas (GHG) emissions from the agricultural sector, mainly due to CH4 emissions from continuously flooded fields. Alternate Wetting and Drying (AWD) is a ... -
