Historical relative humidity measurements from the DMC network

Meteorological Directorate of Chile

datasetViewer.description

Relative humidity is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on the temperature and pressure of the system of interest. This is one of the variables recorded by the meteorological network of the Chilean Meteorological Directorate (DMC). This collection contains the information stored by 488 stations that have recorded, at some point, the relative humidity since 1952, spaced every hour. It is important to note that not all stations are currently operational. The data is updated directly from the DMC's web services and can be viewed in the Data Series viewer of the Itrend Data Platform. In addition, a historical database is provided in .npz* and .mat** format that is updated every 30 days for those stations that are still valid. *To load the data correctly in Python it is recommended to use the following code: ```python import numpy as np with np.load(filename, allow_pickle = True) as f: data = {} for key, value in f.items(): data[key] = value.item() ``` **Date data is in ```datenum``` format, and to load it correctly in ```datetime``` format, it is recommended to use the following command in MATLAB: ```python datetime(TS.x , 'ConvertFrom' , 'datenum') ```
