Humidity observations in the Arctic troposphere over Ny-Ålesund, Svalbard based on 15 years of radiosonde data
Humidity Arctic troposphere Ny-Å lesund Svalbard
2008/12/10
Water vapour is an important component in the radiative balance of the polar atmosphere. We present a study covering fifteen years of data of tropospheric humidity profiles measured with standard radi...
Signature of Arctic surface ozone depletion events in the isotope anomaly (Δ17O) of atmospheric nitrate
Arctic surface ozone isotope anomaly atmospheric nitrate
2008/12/3
We report the first measurements of the oxygen isotope anomaly of atmospheric inorganic nitrate from the Arctic. Nitrate samples and complementary data were collected at Alert, Nunavut, Canada (82°30 ...
Impacts of climate change on air pollution levels in the Northern Hemisphere with special focus on Europe and the Arctic
climate change air pollution Northern Hemisphere Europe the Arctic
2008/11/11
The response of a selected number of chemical species is inspected with respect to climate change. The coupled Atmosphere-Ocean General Circulation Model ECHAM4-OPYC3 is providing meteorological field...
Chemical ozone loss in winter 1991–1992 is recalculated based on observations of the HALOE satellite instrument, Version 19, ER-2 aircraft measurements and balloon data. HALOE satellite observations a...
Intercomparison of UV-visible measurements of ozone and NO2 during the Canadian Arctic ACE validation campaigns: 2004–2006
UV-visible measurements ozone NO2 Canadian Arctic ACE
2008/11/3
The first three Canadian Arctic ACE validation campaigns were held during polar sunrise at Eureka, Nunavut, Canada (80° N, 86° W) from 2004 to 2006 in support of validation of the ACE (Atmospheric Che...
Volatile organic compound ratios as probes of halogen atom chemistry in the Arctic
volatile organic compound ratios halogen atom chemistry arctic
2008/11/3
Volatile organic compound concentration ratios can be used as indicators of halogen chemistry that occurs during ozone depletion events in the Arctic during spring. Here we use a combination of modeli...
Changes in aerosol properties during spring-summer period in the Arctic troposphere
aerosol properties spring-summer period Arctic troposphere
2008/10/28
The change in aerosol properties during the transition from the more polluted spring to the clean summer in the Arctic troposphere was studied. A six-year data set of observations from Ny-Ålesun...
