Raman lidar in operational meteorology

Bertrand Calpini, Valentin Simeonov, Todor Dinoev, Ilya Serikov

Water vapor and temperature spatial distribution and their temporal evolution are among the most important parameters in numerical weather forecasting and climate models. The operational relative humidity/temperature profiling in meteorology is carried out ...

Instrumental correction of the uneven PMT aging effect on the calibration constant of a water vapor Raman lidar

Bertrand Calpini, Valentin Simeonov, Salomon Fastig

The water vapor profile derived from Raman lidar measurements is obtained by taking the ratio of water vapor and nitrogen Raman-shifted signals. The proportionality factor that converts the signal ratio to water vapor/air mixing ratio is referred to as lid ...

Raman Lidar for Meteorological Observations, RALMO - Part 2: Validation of water vapor measurements

Bertrand Calpini, Valentin Simeonov

The Raman Lidar for Meteorological Observations (RALMO) was installed at the MeteoSwiss Regional Center of Payerne, Switzerland, in summer 2008. One of its aims is to provide continuous vertical profiles of tropospheric water vapor during day and night at ...

Raman Lidar for Meteorological Observations, RALMO - Part 1: Instrument description

Bertrand Calpini, Hubert van den Bergh, Valentin Simeonov, Pablo Roberto Ristori, Todor Dinoev, Marc Parlange

A new Raman lidar for unattended, round-the-clock measurement of vertical water vapor profiles for operational use by the MeteoSwiss has been developed during the past years by the Swiss Federal Institute of Technology, Lausanne. The lidar uses narrow fiel ...
