Danum/Malua Compiled Climate Data 1985 to 2025

Description

A compiled dataset containing key climatic variables collected at the weather stations within the Danum Valley Field Center and Malua basecamp between 1985 to 2025.  Key climatic variables that were collected include daily minimum and maximum temperatures (in celcius), daily relative humidities at 8 am and 2 pm, daily rainfall (in mm), and periods when the Sun is present (in hours).

Note for users:

1. In the case for Danum, measurements taken for temperatures and relative humidities were inconsistent prior to 1990 so do not be alarmed with the huge amount of NAs during this period. There is also long periods of no measurements (>6 months) in 2017 due to data loggers not working properly.
2. In the case for Malua, consistent measurements for temperatures and relative humidities were taken only after 2008. Also, measurements taken between January 2020 to July 2023 were inconsistent due to the COVID-19 pandemic.
3. In all cases, we included period of Sun only after 2008.

Version 4.0:

1. We have included climate data collected from January to June of 2025 for both weather stations.
