This framework was adapted from several previous studies and frameworks including Ryan and Deci’s (2000) self-determination theory, Dunwoody and Griffin’s (2015) risk information seeking and processing (RISP) conceptual model, and Earle’s (2010) review using the consensus model of trust. Therefore, usefulness in this context will refer to how weather radar is used for practical, decision-making purposes, as a source of information about precipitation. By definition, useful means to be “capable of being put to use” or “of a valuable or productive kind” ( ). (2018) created this framework to assess the National Weather Service’s weather radar website display. (2018) to determine which factors may influence the perceived usefulness of a radar display (see Fig. To focus our study, a conceptual framework was used from Saunders et al. With a large variety of sources to choose from for weather information, it is important to discern why individuals choose to view radar as a source of information about precipitation and storm events. Therefore, little is known about what motivates someone to use a radar display or how useful individuals find a radar display as a decision-making tool. 2012), few include the use of weather radar displays. 2018 Sherman-Morris and Lea 2016 Stewart 2009 Stewart et al. While there is a growing volume of articles, both peer-reviewed and published in the media, that focus on how people access, use, and perceive weather forecast information ( Demuth et al. Any individual can view a radar display on a television, computer, or tablet or download a radar application on a smartphone. With advancements in technology, weather radar displays are widely available and popular outside of the meteorological and emergency management communities. Meteorologists, among other communities, rely on these data to determine the location and intensity of precipitation and the direction of winds, and to detect other objects such as migrating insects or debris from a tornado. Radar has been used for meteorological purposes since the 1940s and is a critical tool for forecasting the weather ( Henson 2010). Keywords: Social Science Radars/Radar observations Communications/decision making The majority of respondents indicate they use a smartphone device to view radar most often and that participating in outdoor activities was an important motivator for using radar. Respondents who reported greater accuracy for the location of precipitation on a radar display were more likely to rate the radar display as being more useful. This study finds that survey respondents in the Tampa Bay area frequently view a weather radar display and find it to be a very useful tool. Data were collected using an online survey instrument. The final goal of this study is to identify which activities motivate a Tampa Bay resident to view weather radar. It also investigates what information radar users find most important when choosing to view a radar display, as well as what electronic sources are used most often to access weather radar. This study is a novel exploration of how Tampa Bay area residents use radar and identifies several important factors that influence how useful radar is perceived to be as a decision-making tool. However, little is known about how individuals use and perceive information from weather radar displays, despite the existence of radar since the 1940s. In addition to weather forecast information, people are seeking and using a variety of weather information sources that provide them with current conditions and include tools such as satellite images and weather radar displays. Weather information is widely available across many media platforms, including televisions, computers, smartphones, and tablets.
