Measurement report: Contribution of atmospheric new particle formation to ultrafine particle concentration, cloud condensation nuclei, and radiative forcing – results from 5-year observations in central Europe

Publikováno v: Atmospheric Chemistry and Physics, Vol 24, Pp 10667-10687 (2024)

As an important source of sub-micrometer particles, atmospheric new particle formation (NPF) has been observed in various environments. However, most studies provide little more than snapshots of the NPF process due to their underlying observations b

Measurement report: Hygroscopicity of size-selected aerosol particles in the heavily polluted urban atmosphere of Delhi: impacts of chloride aerosol

Autor: A. K. Mandariya, A. Ahlawat, M. Haneef, N. A. Baig, K. Patel, J. Apte, L. Hildebrandt Ruiz, A. Wiedensohler, G. Habib

Publikováno v: Atmospheric Chemistry and Physics, Vol 24, Pp 3627-3647 (2024)

Recent research has revealed the crucial role of wintertime, episodic high chloride (H-Cl) emissions in the Delhi region, which significantly impact aerosol hygroscopicity and aerosol-bound liquid water, thus contributing to the initiation of Delhi f

Analysis of atmospheric particle growth based on vapor concentrations measured at the high-altitude GAW station Chacaltaya in the Bolivian Andes

Publikováno v: Atmospheric Chemistry and Physics, Vol 24, Pp 1315-1328 (2024)

Early growth of atmospheric particles is essential for their survival and ability to participate in cloud formation. Many different atmospheric vapors contribute to the growth, but even the main contributors still remain poorly identified in many env

ACCURACY ANALYSIS FOR AUTOMATIC ORIENTATION OF A TUMBLING OBLIQUE VIEWING SENSOR SYSTEM

Autor: K. Stebner, A. Wieden

Publikováno v: The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol XL-3/W1, Pp 131-136 (2014)

Dynamic camera systems with moving parts are difficult to handle in photogrammetric workflow, because it is not ensured that the dynamics are constant over the recording period. Minimum changes of the camera’s orientation greatly influence the proj
