Abstract:
I have monitored temperature and precipitation at eight locations across a 1500m elevation gradient along Volcan Cacao in the Area de Conservacion Guanacaste (ACG) in northwestern Costa Rica since 2013 (January 2026 inclusive). This deposition includes air temperature data collected between March 2013 and September 2023. Air temperatures were recorded using either a HOBO RG3M Temperature and Rain Gauge Data Logger or an Onset HOBO UA-001-64 Pendant Temperature Data Logger or an Onset HOBO MX2202 Pendant Wireless Temperature Data Logger that recorded temperature every15 minutes each day. Datalogger is approximately 1.5 m above the ground. This deposition includes precipitation data collected between March 2013 and January 2026 as recorded using a HOBO RG3M Temperature and Rain Gauge Data Logger where each event logged was 0.2 ml. The deposition includes soil temperature data collected between June 2021 and January 2026. Temperature was recorded using an Onset HOBO MX2202 Pendant Wireless.Temperature Data Logger that recorded temperature every15 minutes each day. Datalogger is buried approximately 10-15 cm below the surface. This deposition includes measurements of soil chemistry as recorded in the field by an HH2 Moisture Meter Wet Sensor (Wet-2) (Delta T Devices, Cambridge, England) in February and August 2014. Inorganic elemental analysis was completed at the University of Guelph Laboratory Services by inductively coupled plasma optical emission spectrometry (ICP-OES) for: Calcium, Magnesium, Phosphorous, Potassium, Sodium, Sulphur, and Iron. A second analysis of elements in soil was conducted at SGS Argifood Laboratories (ug/g) by ICP using ammonium acetate extraction for P, K, Mg and Na. (2026-02-18)
