We launched a new tool – the NEWA Degree Day Calculator! Get the accumulated degree days for a time period of your choosing. Also select from 11 base temperatures (4C, 32F, 40F, 43F, 45F, 48F, 50F, 86F/50F, 55F, 47.14F, 14.3C) plus two calculated using the Baskerville Emen formula (43F and 50F). Access it under the Weather Data main menu or directly at http://newa.cornell.edu/index.php?page=degree-day-calculator.
