The Nevada Research Data Center (NRDC) is a data portal sponsored by The National Science Foundation and hosts a number of data services that affords users access to climate data from project sites throughout Nevada. This paper entails a study of the usability of these data services and layout across two versions of the NRDC portal, the current production version and a new in-development version. The experiment features a series of tasks in which subjects of the study undertake for each iteration and service, and providing feedback. Overall, participants of this study required 90 to 100 seconds and 30 to 100 mouse clicks to complete tasks, while following usage averaged 30 seconds and 15 mouse clicks. This implied a strong learning curve on each of the data services with the open chance of a user being overtly lost. Additionally, feedback from participants indicated an average preference rating of 4.0 where 1 represents a strong preference for the current iteration of the NRDC interface and 5 being the in-development iteration. From these results, participants have shown a full preference to the in-development iteration.
