Overview
The RM Young 41382 probe combines a high accuracy, capacitance-type humidity sensor and precision platinum RTD temperature sensor in one probe. The sensor is mounted in a weatherproof junction box for convenient wiring. Output options are available for 0-1 VDC, and 4-20mA.
Deployment
For accurate measurements, the RM Young 41382 relative humidity and temperature probe should be installed in a protective radiation shield. Use of the probe without a radiation shield may result in large errors due to solar heating. The probe installs easily in the Model 41003P naturally ventilated or Model 43502 aspirated shield.
Design
The relative humidity and temperature probe is designed to offer years of service with minimal maintenance. As with most humidity sensors, humidity calibration may drift slightly with time. Recalibration will restore the probe to acceptable limits.
- Output Signal: 0-1 VDC
- Power Required: 8 mA
- Temp Calibrated Measuring Range: -50 to 50 C
- Temp Response Time: 10 seconds (without filter)
- Temp Accuracy at 0 C: +/-0.3 C
- Temp Sensor Type: Platinum RTD
- RH Measuring Range: 0-100% RH
- RH Accuracy at 20 C: +/-2% RH,
- RH Stability: Better than +/-1% RH per year
- RH Response Time: 10 seconds (without filter)
- RH Sensor Type: Rotronic Hygromer

UNC's industry-standard water quality profiling platforms get upgrade
The University of North Carolina Institute Of Marine Sciences has a history with profiling platforms. UNC engineers and scientists have been building the research floaters for 10 years in a lab run by in Rick Luettich, director of the institute. 
 UNC scientists and engineers developed their own autonomous vertical profilers to take water quality readings throughout the water column. They have three profilers placed in the New and Neuse rivers. The profilers are designed to drop a payload of sensors to an allotted depth at set time intervals. Instruments attached take readings continuously on the way down and up. 
 Data collected by the profilers has been used to study water related issues such as infectious disease and sediment suspension.

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.

California Polytechnic State University, San Luis Obispo (Cal Poly, SLO), has been monitoring Morro Bay for decades, and while the monitoring program has changed over the years, the dedication to monitoring the bay has remained the same. 
 
The project started in 2006 as a Packard Foundation-funded initiative to monitor water quality flowing in and out of Morro Bay. The goal at the time was to use the data collected to develop and inform an ecosystem-based management plan in collaboration with the Morro Bay National Estuary Program (MBNEP). 
 
Since the estuary was the focus at the time, researchers were monitoring water flowing into the estuary from Chorro Creek and Los Osos Creek.
