Baseline surface radiation network (BSRN/WCRP) New precision radiometry for climate research
To support climate research, the World Climate Research Programme (WCRP) initiated a new radiometric network, the Baseline Surface Radiation Network (BSRN). The network aims at providing validationExpand
The global energy balance from a surface perspective
In the framework of the global energy balance, the radiative energy exchanges between Sun, Earth and space are now accurately quantified from new satellite missions. Much less is known about theExpand
The energy balance over land and oceans: an assessment based on direct observations and CMIP5 climate models
The energy budgets over land and oceans are still afflicted with considerable uncertainties, despite their key importance for terrestrial and maritime climates. We evaluate these budgets asExpand
Climatology and time series of surface meteorology in Ny-Ålesund, Svalbard
Abstract. A consistent meteorological dataset of the Arctic site Ny-Alesund (11.9° E, 78.9° N) spanning the 18 yr-period 1 August 1993 to 31 July 2011 is presented. Instrumentation and data handlingExpand
Climatology of the three coastal Antarctic stations Dumont D'urville, Neumayer and Halley
Long term air and snowfall chemistry measurements have been performed at the three coastal Antarctic stations Dumont d'Urville (66°40′S, 140°1′E), Neumayer (70°39′S, 8°15′W), and Halley (75°35′S,Expand
Parameterization of the downward long-wave radiation at the Earth's surface in polar regions;Parameterisierung der bodennahen Gegenstrahlung in polaren Regionen
Various parameterization schemes for the downward long-wave radiation at the Earth's surface which have been frequently applied in sea ice and snow cover models are tested with the aid of one year'sExpand
The Polar Ozone and Aerosol Measurement (POAM) III instrument and early validation results
Polar Ozone and Aerosol Measurement (POAM) III, a follow-on to the successful POAM II, is a spaceborne experiment designed to measure the vertical profiles of ozone, water vapor, nitrogen dioxide,Expand
Measurements of spectral snow albedo at Neumayer, Antarctica
Abstract. Spectral albedo in high resolution, from 290 to 1050 nm, has been measured at Neumayer, Antarctica, (70°39' S, 8°15' W) during the austral summer 2003/2004. At 500 nm, the spectral albedoExpand
Seasonal variability of crustal and marine trace elements in the aerosol at Neumayer station, Antarctica
Atmospheric trace element concentrations were measured from March 1999 to December 2003 at the Air Chemistry Observatory of the German Antarctic station Neumayer, by inductively coupledExpand
Dynamics and chemistry of tropospheric bromine explosion events in the Antarctic coastal region
[1] We investigate chemistry and dynamics of bromine explosion events during Antarctic spring of 1999 and 2000 using ground-based differential optical absorption spectroscopy (DOAS) observations ofExpand
