Researchers in the University of Iowa have discovered the first two genes involved in moisture sensing. The discovery also reveals a “two-sensor” hygrosensing system in fruit flies that may allow the flies to detect subtle changes in humidity — an ability that is critical for the flies’ survival.

Space borne climate research
Posted by GBoyd in November 6th 2007
Scientists at The University of Arizona will build a prototype instrument to demonstrate their revolutionary idea for a satellite-borne remote sensing system. It will measure water vapor, temperature and ozone anywhere over the globe with unprecedented vertical resolution and accuracy.
This diagram shows how ATOMMS will be mounted in the gimballed ‘X [...]
King Tut uncovered
Posted by GBoyd in November 5th 2007
The face of Egypt’s most famous ancient ruler, King Tutankhamun, has been put on public display for the first time. Archaeologists took the mummy from its stone sarcophagus and placed it in a climate-controlled case inside his tomb in Luxor’s Valley of the Kings.
The event comes 85 years to the day after the pharaoh’s [...]
How to read a weather map
Posted by GBoyd in November 4th 2007
Weather maps provide a simplified depiction of the current or predicted weather conditions of an area. They can be based on satellite and radar images, recordings from instruments at weather stations, and computer analyses. The most common weather map you’ll come across is a surface analysis, shown here. As they appear on television, in a [...]

Changes in the way weather data are collected may have compromised record-keeping and the ability to predict monsoon thunderstorms, according to a National Weather Service veteran and a University of Arizona meteorologist.
The weather service in Tucson used a launch site for [...]
multi-lingual barometer
Posted by GBoyd in November 3rd 2007
The Vaisala BAROCAP® Digital Barometer PTB330 is a new generation barometer designed for a wide range of high-end atmospheric pressure measurement.
The PTB330 series features extremely high accuracy. The PTB330 incorporates one, two or three BAROCAP® sensors. When two or three sensors are used, the barometer continuously compares the readings of the pressure sensors against one [...]
Humidity & dewpoint transmitters
Posted by GBoyd in November 3rd 2007
The new highly accurate transmitters of the EE33 series are designed for fast and reliable measurement of relative humidity, dew point temperature, absolute humidity and six more climatic measuring quantities under the most demanding conditions.
Neither condensation nor heavy chemical pollutions will affect prompt and reliable measurements. Process pressures as high as 100bar (1450psi) and continuous [...]
