“…Solar radiation in combination with energy balance techniques is also important for estimating photosynthetic activity of vegetation (Merva, 1995), and relationships have been developed for estimating photosynthetically active radiation (PAR) from solar radiation data (e.g., Finch et al, 2004;Xia et al, 2008). Long-term records of solar radiation are essential for evaluating solar as a potential energy source at specific locations (Irizarry-Rivera et al, 2009), and for conducting health related studies (e.g., skin cancer; Johnson, 1973).…”

Knowledge of solar radiation at the ground surface is valuable for many disciplines. In this study, ground-based sensors at Fortuna and Mayaguez, Puerto Rico, were used to calibrate daily-integrated satellite-derived solar radiation. The calibration equations yielded R 2 values of 0.88 and 0.83 at Fortuna and Mayaguez, respectively. A regression equation was also derived based on the combined data from the two locations with an R 2 of 0.87. The calibration equations for Fortuna and UPRM were validated using 283 and 227 days of solar radiation data from 2010, respectively. The combined data equation (intended as an island-wide equation) worked well at UPRM but not at Fortuna. We recommend, for locations other than the study areas, that the uncorrected remotely sensed data be used. At the study sites, the uncorrected data produced reasonably accurate results with a maximum 6.22% error between the mean estimated and measured solar radiation.

Each May since 1984, the American Academy of Dermatology, using dermatologist members and American Cancer Society volunteers, has conducted a National Melanoma/Skin Cancer Prevention Program. Through free patient screenings at hospitals, community centers, and health fairs, more than 600,000 individuals have been reached. Through its educational and screening functions, this program has been considered “one of the finest examples of preventive medicine in the country” and as a model for other mass screening programs. This paper reviews some of the concepts that guide the Academy's screening program, some organizational aspects of the program, its accomplishments to date, and possible future directions.
