Lufft WS502 Multi-Parameter Weather Sensor

Overview
The Lufft family of multi-parameter weather sensors offer a cost-effective, compact alternative for the acquisition of a variety of measurement parameters on land- and buoy-based weather stations. Depending on the model, each sensor will measure a different combination of weather parameters to meet a wide variety of applications. The Lufft WS502 Multi-Parameter Weather Sensor simultaneously measures air temperature, humidity, pressure, solar radiation & wind with an integrated electronic compass for corrected wind direction on moving platforms.

Air Temperature & Humidity
Temperature is measured using a highly accurate NTC-resistor, while humidity is measured using a capacitive humidity sensor. Both sensors are located in a ventilated radiation shield to reduce the effects of solar radiation.

Pressure
Absolute air pressure is measured using a built-in MEMS sensor. The relative air pressure referenced to sea level is calculated using the barometric formula with the aid of the local altitude, which is user-configurable on the equipment.

Wind Speed & Direction
The wind sensor uses four ultrasound sensors which take cyclical measurements in all directions. The resulting wind speed and direction are calculated from the measured run-time sound differential.

Compass
The integrated electronic compass can be used to check the north-south adjustment of the sensor housing for wind direction measurement. It is also used to calculate the compass-corrected wind direction.

Solar Radiation
The pyranometer is intended for shortwave global solar radiation measurements in the spectral range from 300 to 1100nm. The thermopile sensor construction measures the solar energy that is received from the total solar spectrum and the whole hemisphere. The output is expressed in Watts per square meter.

Delaware Environmental Observing System detects rare tornado in state

A University of Delaware monitoring network picked up a tornado that touched down in Newark on June 10, according to a release. Tornadoes are rare in the state, but sensors were there to capture it. The Delaware Environmental Observing System, which supplies data to the National Weather Service, charted the tornado with winds of 65 to 85 mph. The observing system also measured the heavy rain that accompanied the tornado. Experts say a low-pressure system and cold front in the Ohio Valley met with warm air in Delaware, which set off the churning clouds that ultimately generated the tornado. The tornado was picked up by a weather station nearly a half mile away, which measured wind speeds at 20 mph.

USGS weather station network monitors Arctic Alaska's climate

When the U.S. Geological Survey began building their climate and permafrost monitoring network in Arctic Alaska in 1998, there wasn't much precedent for how to build the infrastructure for the instruments in the region's unforgiving environment. That meant the scientists had to learn the particulars on the fly. For example: On the great expanse of flat, barren tundra, a weather station sticks out like a sore thumb to a curious grizzly bear. "The initial stations were pretty fragile," said Frank Urban, a geologist with the USGS Geosciences and Environmental Change Science Center. "So the bear and those stations--the bear won every single time without any problem.

Caring for the Chesapeake: Supporting the Iconic Bay Starts with Good Monitoring Data

The Chesapeake Bay is enormous: the Bay and its tidal tributaries have 11,684 miles of shoreline—more than the entire U.S. west coast. It is the largest of more than 100 estuaries in the United States and the third largest in the world. The Bay itself is about 200 miles long, stretching from Havre de Grace, Maryland, to Virginia Beach, Virginia. But the Chesapeake Bay isn’t just enormous--it’s enormously important. The  Chesapeake Bay Program  reports that its watershed covers about 64,000 square miles and is home to more than 18 million people, 10 million of which live along or near the Bay’s shores.
