Abstract:
|
A synergetic approach for estimation of the nocturnal stable boundarylayer
(SBL) height is presented. Aerosol backscatter from a lidar
ceilometer and potential temperature from a microwave radiometer
(MWR) are combined by using an extended Kalman filter
(EKF). While height-resolved spatial-variance from the ceilometer
backscatter signal provides a signature for the stratification of
aerosols in the SBL, temperature data from the MWR helps to
correctly incorporate information about the thermodynamic stability
of atmosphere. The method is applied to data from a Vaisala
CT25K ceilometer and a Humidity-and-Temperature Profiler (HATPRO)
MWR collected during the HD(CP)2 Observational Prototype
Experiment (HOPE) campaign at Julich, Germany. |
