Historical atm pressure at sea level measurements from the DMC network

Meteorological Directorate of Chile

datasetViewer.description

This pressure measurement is the atmospheric pressure corrected to sea level. It is used in the field of meteorology to compare the air pressures of different places at different heights. The network of the Chilean Meteorological Directorate (DMC) provides information from 317 stations that have recorded, at some point, the pressure since 1941, with data spaced every hour. 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') ```
