After tallying the sentiment and reading the comments, Mollov has been officially named the Featured Geocacher of the Month for July 2013.Mollov – Geocacher of the MonthOne comment shows Mollov’s 360 degree passion for geocaching and its community, “Mollov is one of the most active geocachers in Bulgaria I know and probably the most enthusiastic one as well. His geocaching activities do not end with finding, hiding and maintaining geocaches. If you have seen any of his geocaching adventures on Youtube, or read any of his geocaching articles on his blog, or attended any of the events organized by him, then you probably know why Mollov deserves to be selected as Geocacher of the Month. For all the rest, it would be enough to say that Mollov’s devotion has made geocaching a much more popular activity in Bulgaria. His dedication to the game deserves to be recognized not only in his own country but by the wider geocaching society as well.”Mollov will receive the earned, never for sale, collector’s edition Featured Geocacher of the Month Geocoin, along with a Featured Geocacher of the Month hat and a certificate acknowledging his contribution, signed by two of the founders of Geocaching.com.

An intercomparison of zenith-sky UV-visible spectrometers was held at Camborne, UK, for 2 weeks in September 1994. Eleven instruments participated, from nine different European institutes which were involved with the Second European Stratospheric Arctic and Mid-latitude Experiment (SESAME) campaign. Four instruments were of the Systeme d’Analyse d’Observations Zénithales (SAOZ) type, while the rest were particular to the institutes involved. The results showed that the SAOZ instruments were consistent to within 3% (10 DU) for ozone and 5% for NO2. For ozone the results from these instruments agreed well with total ozone measurements by Dobson and Brewer spectrophotometers and integrated ozonesondes when the air mass factors for the SAOZ were calculated using the ozonesonde profiles. Differences of up to 10% in ozone and 30% in NO2 were found between different instruments. In some cases these differences are attributable to the different absorption cross sections used in the analysis of the spectra, but other discrepancies remain to be investigated. A prominent source of error identified in the campaign was uncertainty in the derivation of the amount of absorber in the reference spectrum, which can contribute an error of up to 3% (10 DU) in ozone and 1.5×1014 molecules cm−2 in NO2.
