Exploring mainland chinese and dutch high school students' conceptions of learning technology: A phenomenographic analysis

The aims of the study were to investigate high school students' conceptions of learning technology (COLT) in mainland China and the Netherlands, and tried to explain the differences from different educational and social backgrounds. The phenomenographic method was used, interviewing 85 students from both counties. The findings of the research...

Wind Hazard and Turbulence Monitoring Atairports With Lidar, Radar, and Mode-S Downlinks: The UFO Project

This article presents the prospects of measurement systems for wind hazards and turbulence at airports, which have been explored in the Ultrafast Wind Sensors (UFO) project. At France’s Toulouse–Blagnac Airport, in situ, profiling, and scanning sensors have been used to collect measurements, from which wind vectors and turbulence intensities are...

InSAR based validation of MERIS IWV cloud gap filling using GPS IWV

High spatial resolution integrated water vapor (IWV) estimates are available from the MERIS spectrometer on board of Envisat. Unfortunately cloud cover results in loss of a large amount of MERIS IWV pixels. Here methods are presented for filling cloud gaps in MERIS IWV scenes, first, by directly interpolating remaining pixels not affected by...

Validating time series of a combined GPS and MERIS Integrated Water Vapor product

Increased knowledge of atmospheric water vapor can improve weather predictions and is expected to reduce errors in products derived from GPS and (In)SAR data. At GPS ground stations Integrated Water Vapor (IWV) is estimated from the GPS signal delay with a high temporal resolution. The Envisat MERIS spectrometer obtains spatially dense IWV...
