Liverpool manager Brendan Rodgers was left disappointed following his side’s 1-1 draw with Chelsea in the first leg of their League Cup semi-final tie at Anfield.The Reds were the more dominant team throughout Tuesday night’s clash but fell behind against the run of play in the first-half through Eden Hazard’s penalty.Rodgers’ men maintained pressure on their opponents, who managed just two shots on target in the 90 minutes, and eventually equalised after the break courtesy of Raheem Sterling’s fine solo goal.They had a handful of chances to win the game in the final moments, too, but Sterling, Jordan Henderson and substitute Adam Lallana all had decent efforts well saved by Thibaut Courtois.A frustrated Rodgers felt his side would have been worthy winners, but also said the Redmen’s bright performance will give them confidence ahead of next week’s return trip to Stamford Bridge.The Northern Irishman said: “I’m delighted with the performance, disappointed with the result.“I thought we deserved to win the game, we showed wonderful character. We went behind to their only shot on target but some of our play, taking the game to Chelsea, was very impressive.“It was a wonderful performance and sets up the second leg perfectly. They’re at home and will have to open up a wee bit more.“My players were super tonight, they were tactically brilliant and I’ve got no complaints.“We deserved to win the game and only managed a draw, but our performance gives us great confidence for the second-leg.”
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.
