摘要:Understanding the atmospheric distribution of water (H 2 O) is crucial for global warming studies and climate change mitigation. In this context, reliable satellite data are extremely valuable for their global and continuous coverage, once their quality has been assessed. Sh...

摘要:Abstract(#br)Radionuclides 137 Cs and 90 Sr and total beta activity were determined from air filters collected in Rovaniemi (Finnish Lapland) in 1965–2011. Nuclear contamination sources present in the air filter samples as well as temporal changes in radionuclide concentrati...

摘要:ABSTRACT(#br)On 22 January 1997 1200 UT, the routine radiosonde from Sodankylä, Finland, measured a record low temperature of − 94.5 °C at 26 km. Mesoscale numerical simulations indicate strong mountain wave activity on this day. Two stratospheric temperature minima are simu...

摘要:Abstract(#br)After the well-reported record loss of Arctic stratospheric ozone of up to 38% in the winter 2010–2011, further large depletion of 27% occurred in the winter 2015–2016. Record low winter polar vortex temperatures, below the threshold for ice polar stratospheric ...

摘要:Abstract(#br)This paper presents a novel retrieval algorithm for the rapid retrieval of the carbon dioxide total column amounts from high resolution spectra in the short wave infrared (SWIR) range observations by the Greenhouse gases Observing Satellite (GOSAT). The algorithm per...

摘要:Abstract(#br)The absence of LIDAR depolarization in a polar cirrus observed above Sodankyla (Finland) showed the presence of spherical particles at −65°C. The presence of pure liquid water is excluded, since homogeneous freezing should occur at or above −40°C. The cirru...

摘要:Abstract(#br)Measurements of tropospheric ozone at three sites at the Arctic Circle in the Finnish Lapland are presented. The variability of ground-level ozone over the diurnal and seasonal cycles in 1992–1993 is discussed for the sites of Oulanka and Pallas. The variability...

摘要:This study evaluated three bias correction methods of systematic biases in column-averaged dry-air mole fraction of water vapor (XH2O) data retrieved from Greenhouse Gases Observing Satellite (GOSAT) Short-Wavelength Infrared (SWIR) observations compared with ground-based da...
