High-frequency urban measurements of molecular hydrogen and carbon monoxide in the United Kingdom
High-frequency urban measurements molecular hydrogen carbon monoxide the United Kingdom
2010/8/13
High-frequency measurements of atmospheric molecular hydrogen (H2) and carbon monoxide (CO) were made at an urban site in the United Kingdom (UK) from mid-December, 2008 until early March, 2009. Very ...
A 15 year record of high-frequency, in situ measurements of hydrogen at Mace Head, Ireland
high-frequency hydrogen Mace Head Ireland
2010/2/21
Continuous high-frequency measurements of atmospheric molecular hydrogen have been made at Mace Head atmospheric research station on the west coast of Ireland from March 1994 to December 2008. The pre...
Discriminating low frequency components from long range persistent fluctuations in daily atmospheric temperature variability
long range persistent fluctuations daily atmospheric temperature low frequency components
2009/7/22
This study originated from recent results reported in literature, which support the existence of long-range (power-law) persistence in atmospheric temperature fluctuations on monthly and inter-annual ...
Isolated lower mesospheric echoes seen by medium frequency radar at 70° N, 19° E
Isolated lower mesospheric echoes medium frequency radar
2009/1/20
We have noted sporadic instances of strong isolated reflections of medium frequency (MF) radar waves from the mesosphere from as low as 50 km altitude and have devised a set of criteria for isolating ...
Analysis of the frequency-dependent response to wave forcing in the extratropics
frequency-dependent wave forcing extratropics
2009/1/15
A quasigeostrophic model for the frequency-dependent response of the zonal-mean flow to planetary-wave forcing at Northern Hemisphere (NH) midlatitudes is applied to 4-D-Var ECMWF analysis data for s...
Three-dimensional effects in polarization signatures as observed from precipitating clouds by low frequency ground-based microwave radiometers
Three-dimensional effect polarization signatures precipitating clouds low frequency ground-based microwave radiometers
2009/1/15
Consistent negative polarization differences (i.e. differences between the vertical and the horizontal brightness temperature) are observed when looking at precipitating systems by ground-based radiom...
Photolysis frequency measurement techniques: results of a comparison within the ACCENT project
Photolysis frequency measurement ACCENT project
2008/11/19
An intercomparison of different radiometric techniques measuring atmospheric photolysis frequencies j(NO2), j(HCHO) and j(O1D) was carried out in a two-week field campaign in June 2005 at Jülich, Germ...
Assessment of high (diurnal) to low (seasonal) frequency variations of isoprene emission rates using a neural network approach
variations isoprene emission rates neural network
2008/11/4
Using a statistical approach based on artificial neural networks, an emission algorithm (ISO-LF) accounting for high to low frequency variations was developed for isoprene emission rates. ISO-LF was ...
