Ash Detection Technology
Senior NILU Scientist Dr. Fred Prata has been working on an ash detection technology for over 15 years and today he received the credit he deserves at a major press conference in London.  The airborne solution called AVOID is a system being developed which will provide pilots with roughly 6-7 minutes warning of ash clouds. The system uses IR technology and proprietary algorythms to distinguish ash from water vapor.  Design, testing and certification will be taking place over the next few months and will be commercialized by daughter company Nicarnica AS.  The AVOID system is ...
WFS Technologies led consortium delivers world’s first real-time networked coastal erosion monitoring system
A WFS Technologies led consortium has delivered the world’s first real-time networked coastal erosion monitoring system. More than half of the world"s population lives within 60 km of a coastline zone. As changing global climate and rising sea levels speed up coastal erosion, researchers need to monitor what is happening beneath the surface of the sea.  Understanding coastal erosion has typically been by observation and measurement of exposed coastal areas rather than using quantitative data.  The estimation of these effects has left us with only partial picture of what is really ...

The Lost Formulas - Humidity Conversion Made Easy

This document provides formulas and derivations to help you understand the various humidity parameters and what variables do or do not affect the parameter.  For example, temperature is a critically important variable for the parameter "relative humidity".   However, temperature changes to the air (or gas) do not affect the parameter "dew point temperature".

Conversion formulas include:

  • Relative Humidity
  • Water vapor saturation pressure
  • Dewpoint temperature
  • Pressure dewpoint
  • Wet bulb drybulb to RH 
  •  ... and more
