Between June 2015 and November 2020 precipitation samples (N = 485) were collected at the Base Crestones shelter (-83.480°, 9.460°, 3400 m asl) on the Pacific slope of Chirripó, using a passive collector. Samples were collected manually on every rainy day at 07:00 hr (−06:00 GMT). Lake water samples were collected at Lake Ditkevi (-83.481°, 9.469°, 3506 m asl) following a roughly biweekly/monthly sampling plan. Stable isotope analyses of precipitation and lake water samples were conducted at the Stable Isotope Research Group facilities of the National University (Heredia, Costa Rica) using a cavity ring down spectroscopy water isotope analyzer L2120-i (Picarro, USA) and a LWIA-45-EP water isotope analyzer (Los Gatos, USA).
