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.

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.

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.

Solar Radiation
The pyranometer is based on the Kipp & Zonen CMP10 that uses the ISO 9060 Secondary Standard for measurements in the spectral range from 285 to 2800nm. The output is expressed in Watts per square meter.

As Arctic Permafrost Thaws, Northernmost Lakes Brown

More than 250 million years ago, massive volcanic activity in the region of what is now Siberia caused “The Great Dying,†a colorful name for the Permian mass extinction that wiped out most of the life on Earth at the time. Once the volcanic activity finally calmed down after a respectable one million years, about 96 percent of life in the ocean and 80 percent of life on land was gone. About 500 gigatons of carbon were left behind in that region, and as the Earth cooled, that carbon was sealed in the Permafrost that covers much of Siberia today. Permafrost is simply ground that stays frozen at or below 0° Celsius (32° Fahrenheit) all of the time. It does not necessarily contain ice; as long as it remains frozen solid, even completely dry ground is permafrost.

Volunteer Water Quality Monitoring Networks at the Heart of Citizen Science Movement

Lately, citizen science initiatives have been getting noticed by laypeople and mainstream media outlets. As everyday people become aware of ways they can get involved in actual scientific research, more of them are doing so—especially teachers and parents working with children. But this citizen science wave isn't actually a new thing. It has been growing outward from its core in volunteer water quality monitoring networks for years. Around the country, volunteers have been quietly monitoring the water quality in lakes, streams, rivers, marshes, and other surface waterways for decades. These highly successful programs have been supporting better water quality in communities across America, and in doing so have also formed the heart of the modern citizen science movement.

US Steel Dumping Chromium: Citizens Fighting for Lake Michigan, and Drinkable Water

If you remember the movie “Erin Brockovich,†you are already familiar with hexavalent chromium, a toxic substance that was contaminating the drinking water of people in California in the movie ( and in real life ). Although on the silver screen there was a very satisfying Hollywood resolution to the problem, there has not yet been such a happy ending in real life. The dumping of the hexavalent chromium by PG&amp;E that the film documented took place in the 1950s and 1960s, although the company didn't tell anyone about the problem until the late 1980s. Based on current litigation around the Illinois and Indiana shores of Lake Michigan, startlingly little has changed.
