Scanning electron microscopy and molecular dynamics of surfaces of growing and ablating hexagonal ice crystals
electron microscopy molecular dynamics growing and ablating hexagonal ice crystals
2010/8/12
We present the first clearly resolved observations of surfaces of growing and ablating hexagonal ice crystals using variable-pressure scanning electron microscopy. The ice surface develops trans-prism...
Evidence of ice crystals at cloud top of Arctic boundary-layer mixed-phase clouds derived from airborne remote sensing
ice crystals Arctic boundary-layer mixed-phase clouds airborne remote sensing
2009/12/31
The vertical distribution of ice crystals in Arctic boundary-layer mixed-phase (ABM) clouds was investigated by airborne remote-sensing and in situ measurements during the Arctic Study of Tropospheric...
On the importance of small ice crystals in tropical anvil cirrus

2009/8/7
In situ measurements of ice crystal concentrations and sizes made with aircraft instrumentation over the past two decades have often indicated the presence of numerous relatively small (< 50 μm diamet...
In-situ observations of aerosol particles remaining from evaporated cirrus crystals: Comparing clean and polluted air masses
aerosol particles cirrus crystals clean and polluted air masses
2009/3/11
In-situ observations of aerosol particles contained in cirrus crystals are presented and compared to interstitial aerosol size distributions (non-activated particles in between the cirrus crystals). T...
Thermal stability analysis of particles incorporated in cirrus crystals and of non-activated particles in between the cirrus crystals: comparing clean and polluted air masses
cirrus crystals non-activated particles cirrus crystals air masses
2009/3/4
A thermal volatility technique is used to provide indirect information about the chemical composition of the aerosol involved in cirrus cloud formation. The fraction of particles that disappears after...
In-situ observations and modeling of small nitric acid-containing ice crystals
In-situ observation nitric acid-containing ice crystals
2008/12/12
Measurements in nascent ice forming regions are very rare and help understand cirrus cloud formation and the interactions of trace gases with ice crystals. A tenuous cirrus cloud has been probed with ...
Formation of large (≃100 μm) ice crystals near the tropical tropopause
formation ice crystals tropical tropopause
2008/11/3
Recent high-altitude aircraft measurements with in situ imaging instruments indicated the presence of relatively large (≃100 μm length), thin (aspect ratios of ≃6:1 or larger) hexagonal pl...
