Details

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.

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.

Precipitation
Tried and tested radar technology is used to measure precipitation. The precipitation sensor works with a 24GHz Doppler radar, which measures the drop speed and calculates precipitation quantity and type by correlating drop size and speed.

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.

In-Home Water Testing: A Talk With the Creator of Tap Score by SimpleWater

In the wake of various water quality crises from Flint, Michigan and Puerto Rico, there is a growing interest and demand among consumers for home water testing. Enter DIY water testing kits like Tap Score by SimpleWater. Tap Score in particular was conceived of and launched by former UC Berkeley grad student John Pujol and co-founder and CTO Julio Rodriguez. “In 2015 we began testing small and rural communities for arsenic in their water,” Pujol explains. “We found it much more frequently than we expected, and also discovered that people in these towns greatly appreciated someone telling them what was in their water and how to fix it.

Hidden Underground Nitrate Pollution Threatens Groundwater Worldwide

For most of us, when we think of nitrate and agricultural pollution, we think of the nitrate that comes from fertilizers and leaches quickly through the soil. The effects of this kind of pollution are realized quickly, but researchers from Lancaster University and the British Geological Survey have recently revealed an underground time bomb of nitrate in rock. In the recent paper , lead author and hydrogeologist Matthew Ascott and the team quantified the vast amounts of nitrate that exist within the layers of rock between the soil and groundwater tables for the first time. They discovered that there is about twice as much nitrate lurking in this rocky vadose zone than there is in the soil—up to 180 million tons—nitrate that has been omitted from global scale nitrogen budgets.

Water in the Desert: The USGS and Arizona's Water Challenges

In a state that knows water is perhaps the single most decisive factor in its continued existence, the Arizona Water Center (AWC), part of the United States Geological Survey (USGS), plays a critically important role. James Leenhouts, Director of the AWC and a hydrologist by training, has lived in Arizona for decades, and devoted his career to helping Arizonans cope with the unique challenges water presents. “A key part of what we do is provide information for resource managers to answer their questions,” Leenhouts explains. “For example, if someone wants to put wells in a certain place in the aquifer, how will it affect nearby wells?” It's a fair question.
