Weather Data: Why Accuracy is More Complicated Than You Think

Don’t unwittingly compromise your weather data by underestimating all the factors that influence accuracy. Dr. Colin Campbell discusses what these factors are and how to plan for them.

You need data you can trust

Think weather data accuracy is about sensor specifications? Think again. There are a host of other factors that influence accuracy, and if you don’t understand what they are, your data can steer you in the wrong direction and put your projects at risk. 

What you need to know 

In this 30-minute webinar, Dr. Colin Campbell explains how you can unwittingly compromise your data by underestimating these important factors. Learn:

  • How microclimates influence accuracy 
  • How many measurement sites you need to deal with variability
  • How installation affects accuracy and important best practices to keep in mind
  • Why you need to measure more than just weather parameters to understand what’s happening at your site (critical ancillary measurements)
  • Why the scientific theory behind how a station makes its measurements matters
  • Why models using internet data are not good enough
  • How a station that requires significant maintenance can derail accuracy
  • How using affordable research-grade stations to fill in data gaps between premium-quality setups can be a cost effective way to increase your accuracy
  • Why your data visualization and management system matters in terms of accuracy
  • Case studies that show why you need to think about the big picture


Dr. Colin Campbell has been a research scientist at METER for 20 years following his Ph.D. at Texas A&M University in Soil Physics. He is currently serving as Vice President of METER Environment. He is also adjunct faculty with the Dept. of Crop and Soil Sciences at Washington State University where he co-teaches Environmental Biophysics, a class he took over from his father, Gaylon, nearly 20 years ago. Dr. Campbell’s early research focused on field-scale measurements of CO2 and water vapor flux but has shifted toward moisture and heat flow instrumentation for the soil-plant-atmosphere continuum.
