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 ...
Frequency of occurrence of a certain air temperature at various sites in the Czech Republic

2014/2/26
The present paper analyses the problem of calculation of the average number of hours in a year during which air temperature is lower than a preselected limiting level. A method for estimating the numb...
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...
Extracting a common high frequency signal from Northern Quebec black spruce tree-rings with a Bayesian hierarchical model
Northern Quebec black spruce tree-rings Bayesian hierarchical model
2009/12/3
One basic premise of dendroclimatology is that tree rings can be viewed as climate proxies, i.e. rings are assumed to contain some hidden information about past climate. From a statistical perspective...

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 ...
