Entrevista en Aragón TV
Clip de la entrevista en el informativo Aragón Noticias el domingo 10 de febrero de 2013, recogiendo nuestra investigación sobre erosividad de la precipitación y tendencias en lluvias intensas en el NE peninsular. El mismo tema se trata en esta otra entrevista, publicada por la Agencia SINC: La investigación a la que se alude en los vídeos […]
Daily potential evapotranspiration based on the Hargreaves equation
A handy little R function for computing Hargreaves potential evapotranspiration at the daily scale. # Compute Hagreaves daily pot. evapotranspiration, based on: # tmin: a vector of minimum daily temperatures (ºC) # tmax: a vector of maximum daily temperatures (ºC) # times: a vector of dates corresponding to the temperature observations (POSIXlt) # lat: latitude of the […]
