NYS Mesonet: 2018 year in review

2018 marked the first year of collaboration between the Network for Environment and Weather Applications (NEWA), which is part of the New York State IPM Program at Cornell University, and University at Albany’s New York State Mesonet (NYSM). In March, ten data streams (table 1, figure 1) were established to link NYSM-generated weather data to the NEWA online agricultural decision support system, available for use by agricultural stakeholders across New York State. 2018 was successful, as demonstrated by metrics provided in table 2. 2019 is sure to attract more users to these locations on NEWA as awareness grows of their availability.

The successful collaboration between NEWA and NYS Mesonet was also featured as a showcase in the New York State IPM Program 2017-18 Annual Report. The report can be downloaded from this Cornell eCommons permalink:

Using NEWA to access historical data

Did you know NEWA can load past weather data into your favorite online tool at newa.cornell.edu? It’s the dead of winter which is a perfect time to look back at the 2017 growing season. Read this article to learn more about historical data access using NEWA.

NEWA historical data access

The NEWA website is popular because real-time weather data provide short-term risk assessments during the growing season. But, have you ever looked back and asked yourself what went right or wrong? NEWA tools can also be used to follow insect or disease risk historically through a period of time. You can access this feature using any model or tool available on the NEWA website.


From the ‘Weather Data,’ ‘Pest Forecasts,’ or ‘Crop Management’ dropdown lists in the website navigation bar, select your model of interest.
 Select your pest or disease, State, and Weather station and historical Accumulation end date.
View the historical output.

NEWA historical data access from ‘Inactive’ Stations

Every once in a while, we get a question about historical data from an ‘inactive’ station, which is a NEWA location that no longer transmits to the website. Historical weather data can still be accessed using the hourly or daily weather summary tools.


From the ‘Weather Data’ dropdown list in the website navigation bar, select Hourly Data or Daily Summary.
Scroll to the bottom of available weather stations and find a station of interest.
Choose a month and year from the past.
Get your report.

Farm adaptation: grower programs and resources

A variety of programs and informational resources are available to inform your farm adaptation plan.  NEWA provides real time forecasting tools for insect and disease pests. The Cornell Smart Farming Program provides tools for growers to address longer term climate concerns. The Animal Agriculture in a Changing Climate project provides a specialized set of tools for livestock producers. A number of reports have also been published recently that have information useful to the agricultural community.

Program Description
Network for Environment and Weather Applications (New York State Integrated Pest Management Program) NEWA delivers weather information and apps based on the weather collected that support and advance integrated pest management (IPM) and best management practices for agricultural and green industries. Our vision is that NEWA will become the source for weather-related information for the IPM practitioner in the Northeast
Cornell Smart Farming Program (Cornell Institute for Climate Smart Solutions) The Cornell Climate Smart Farming program is a voluntary initiative that helps farmers in New York and the northeastern US to increase productivity in a sustainable way, reduce greenhouse gas emissions from agricultural production, and increase farm resiliency to extreme weather and climate variability.
Animal Agriculture in a Changing Climate (Cornell University Dairy Environmental Systems Program) Animal Agriculture in a Changing Climate fosters animal production practices that are environmentally sound and economically viable, and that create resiliency for animal producers and their partners.
United States Department of Agriculture Northeast Climate Hub The Northeast Climate Hub, building on capacity within USDA, delivers science-based knowledge and practical information to farmers, ranchers and forest landowners in Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, Maryland, Delaware, West Virginia and D.C
CLN eLearning  (Southern Regional Extension Forestry) CLN eLearning is designed to help Extension Professionals, Professional Crop Advisors and Professional Foresters incorporate climate change into their existing program areas and become Climate Literate. Many of our modules offer Continuing Education Credits from SAF and CCA.

 2014 USDA Climate Change Adaptation Plan  (USDA Office of the Chief Economist)

The U.S. Department of Agriculture (USDA) Climate Change Adaptation Plan presents strategies and actions to address the effects of climate change on key mission areas including agricultural production, food security, rural development, and forestry and natural resources conservation.

The 2014 USDA Climate Change Adaptation Plan includes input from eleven USDA agencies and offices.  It provides a detailed vulnerability assessment, reviews the elements of USDA’s mission that are at risk from climate change, and provides specific actions and steps being taken to build resilience to climate change.

National Climate Assessment: Agriculture (U.S. Global Change Research Program) The full report of the National Climate Assessment provides an in-depth look at climate change impacts on the U.S. and explores the impacts to agriculture.
Climate Impacts on Agriculture and Food  (United States Environmental Protection Agency) Agriculture is an important sector of the U.S. economy. The crops, livestock, and seafood produced  in the United States contribute more than $300 billion to the economy each year. When food-service and other agriculture-related industries are included, the agricultural and food sectors contribute more than $750 billion to the gross domestic product
