Participants can contribute large volumes of data over broad spatial and temporal frames; however, the challenge is to generate data of sufficient quality to be useable in scientific research. Most observations made by citizen-scientists can be independently verified by “experts”. However, verification is more problematic when the phenomena being recorded are short-lived. This article uses a GIS methodology to verify the quality of contrail observations made by the general public as part of the OPAL Climate Survey. We verify observations using datasets derived from a variety of different sources (experts, models and amateur enthusiasts) with different spatial and temporal properties which reflect the complex 3D nature of the atmosphere. Our results suggest that ~70% of citizen observations are plausible, based on favorable atmospheric conditions and the presence or absence of aircraft; a finding which is in keeping with other, more conventional citizen science projects. However, questions remain as to why the quality of the citizen-based observations was so high. Given the lack of supporting data on observers, it is impossible to determine whether the dataset was generated by the activities of many participants or a small but dedicated number of individual observers.

The tutorials will cover the practical applications of thermographic and thermal sensing equipment, thermographic techniques, in-house predictive maintenance, and thermal imaging processing. The conference sessions have evolved over the years as applications have been developed. Session 1, chaired by Ron Lucier, covers Predictive Maintenance Applications for Facilities and Utilities. Papers deal with thermography for facility maintenance and come from the USA, Canada, and Spain. George Baird will chair Session 2, Ethics and Certifications. This session has provided information regarding standards, ethics, and certification for the last four conferences. This year it offers a recommended body of knowledge for thermographic diagnostics and an update of certification by ASNT. We have Sven-Ake Ljungberg and Lee Alien co-chairing the Buildings and Structures session. This session offers some new applications of infrared thermography to buildings and other structures. Presentations are from the USA, Sweden, Spain, and Denmark. Herb Kaplan and Bob Madding co-chair the session on Materials Evaluation. This is a rapidly growing field involving nondestructive evaluations of materials during production and application. This session contains papers from the USA, Canada, and the USSR. Session 5 on Processes and Products is co-chaired by Dennis Dresser and Dag Holmsten. This session contains the keynote address by Mr. Holmsten, Fifteen Years of Thermal Process Monitoring in the Cement Industry: Progress and Development (not available for publication). Jan Eklund and Jon Mohler co-chair Session 6, Research and Development. This session has grown since Thermosense IX and has taken a full day at Thermosense for the past two years. The session with the most international flavor, it contains papers from the USA, India, France, Italy, Korea, and the USSR.
