Overview
It is often said that 80% of data analysis is spent on the process of cleaning and preparing the data. - Hadley Wickham, Chief Scientist at RStudio
Why Oikolab?
Data scientists or analysts often spend days or weeks looking for and processing historical weather data before they can begin their analysis. Here’s where Oikolab comes in – we do the work, so you don’t have to. We save you the most valuable, scarce, and non-renewable resource in the world – your time.
Oikolab has post-processed hundreds of terabytes of weather data that you can access in seconds - whether you require 1 month or 80 years of weather data, downloadable in JSON, CSV or NetCDF format.
Climate & Weather Data for Experts and Researchers
Oikolab data is used by climate and data experts in various industries as well as academic researchers.
