2010/8/16
The refractory black carbon (rBC) mass, size distribution (190–720 nm) and mixing state in sub-micron aerosols were characterized from late February to March 2007 using a single particle incandescence...
Tropospheric water vapour above Switzerland over the last 12 years
Tropospheric water vapour Switzerland last 12 years
2009/8/25
Integrated Water vapour (IWV) has been measured since 1994 by the TROWARA microwave radiometer in Bern, Switzerland. Homogenization techniques were used to identify and correct step changes in IWV rel...
