Current Projects

Next Generation Pitot Anemometer

The Next Generation Pitot Static Tube Anemometer, Pitot20 (internally named because it first became an operational instrument in 2020), resulted from a multi-year collaboration between the Mount Washington Observatory (MWO), General Electric, and the University of Massachusetts-Lowell Engineering Program. The goals included developing a new anemometer for the summit to improve on the current Pitot19 model, simplifying sensor design allowing for easier removal and installation during maintenance and calibration, and exploring the possibility of shortening the length of tubes needed to run from the pitot tube to the pressure transducers located in the weather room. Lastly, MWO set out to explore an upgraded heating system to reduce the accretion of ice during the worst of conditions on the summit.

Support Needed: With more than one year of side-by-side comparison between the Pitot20 and Pitot19 anemometers, a full data analysis is needed to certify this critical new instrument for official reporting purposes. Funding is needed to support researcher time to analyze this data and prepare a manuscript for publication.

Historic Visibility Data Exploration and Analysis

The goal of this project is to explore manual, hourly prevailing visibility data reported from the summit of Mount Washington, NH from roughly 1942 to present for the existence of significant trends or anomalies. If present, significant temporal patterns in visibility will serve as the baseline for future studies of the relationship between visibility and air quality. A public document summarizing the methods and results is available and being shared to external researchers for application to other historic datasets.

Support Needed: Once completed, this foundational work will continue MWO’s focus on exploring, analyzing and publicizing information about all aspects of Mount Washington’s unique climate. Funding is needed to support additional researchers, research support staff and interns to extend this new-found knowledge and help us investigate possible linkages between visibility, air quality, human health, and our changing climate.

Temperature Database Project

Mean Annual Temperature 1935-2020

Mean Annual Temperature 1935-2020

Project goals include producing homogenous hourly and daily maximum and minimum temperature data records from January 1935 to present. MWO will use these records to derive several official research-grade analyses/products, such as a mean annual temperature time series and trends, to support our research and education programs. We are also working to produce a document allowing external researchers the ability to apply the methods developed here to other historic datasets. Finally, we plan to create a digital archive of the paper records by scanning or photographing them.

Support Needed: None required at this time. Work is continuing on a volunteer basis to revise a summary report.

Mount Washington Regional Mesonet Technical Overview

Since early in its history the Observatory has operated and maintained equipment for research, testing and environmental monitoring purposes at its facility on the summit. Since the mid-2000s, we have been developing and deploying a wide network of remote sites that monitor environmental data. This “Mesonet” includes a vertical transect of the atmosphere at 1,000-foot intervals along the Mt. Washington Auto Road and an assortment of high elevation sites at ski area summits, Appalachian Mountain Club huts and other facilities. These remote sites help gather environmental data across the complex terrain of the White Mountains and provide vast opportunities for research and instrument hosting and testing.

Support Needed: Maintenance of this broad network of sensors is both costly and time-consuming. Support is constantly needed to fund calibration and replacement of sensors, solar panels, batteries, data loggers, radios and webcams to ensure a steady flow of high-quality data from these sites.

Monitoring the Intensity of Cosmic Rays From Outer Space

The general nature and purpose of this long-term experiment is to measure variations in the number or intensity of cosmic ray particles reaching Earth. Originally conducted from 1955-2006 under the tutelage of the late Dr. Jack Lockwood and Dr. Jim Ryan of the University of New Hampshire’s Physics Department, it has now been taken over by UNH’s Space Science Center within the Institute for the Study of Earth, Oceans, and Space.

Support Needed:
This project is being led by the University of New Hampshire, with support from MWO.
