Time series data is essentially a collection of data points that are organized in time. Time is frequently the independent variable, and the purpose is usually to forecast the future in time series.
In this article, we will look at the 10 Best Datasets for Time Series Analysis, in order to understand how a certain metric varies over time and to predict future values.
List of the Best Time Series Datasets
-
M4 Competition Dataset - This dataset is a collection of over 100,000 time series of yearly, quarterly, monthly and other (weekly, daily and hourly) data, divided into training and test datasets and is used in the M4 Forecasting Competition, which is an annual competition organized by the International Institute of Forecasters (IIF). The competition aims to evaluate and compare different forecasting methods and models on a diverse set of time series. -
Numenta Anomaly Benchmark (NAB) - The NAB dataset is a collection of real-world and artificial time series data, and is used to evaluate algorithms for anomaly detection. It comprises diverse time series data that cover different domains such as finance, transportation, and environmental monitoring, making it a suitable benchmark dataset for evaluating anomaly detection algorithms. -
The U.S. Census Bureau's International Data Base (IDB) - The IDB dataset includes a variety of demographic and economic time series data for countries around the world. The dataset includes a variety of time series data for countries around the world, such as population, fertility, mortality, migration, and economic indicators, collected and provided by the U.S. Census Bureau, which is an independent agency of the U.S. Federal Government. -
The Google Trends Dataset - This dataset contains the relative popularity of a particular search term over time, as measured by Google. It is also based on the number of Google searches for a particular term, normalized to reflect the popularity of the term relative to the total number of searches on Google. -
The New York City Taxi Dataset - This dataset includes time series data on taxi rides in New York City, including the pickup and drop-off times, locations, transportation prices, the distance of the trips, the fare, and the number of passengers. -
The Beijing Multi-Site Air-Quality Dataset - This dataset includes hourly measurements of air quality at various sites in Beijing. -
The Wikipedia Web Traffic Time Series Dataset -This dataset includes time series data on the traffic to various Wikipedia articles. The dataset provides information on the number of views and visitors for each Wikipedia article, as well as the number of edits and contributors. -
The Global Land and Ocean-Temperature Anomaly Time Series - This dataset includes time series data on the land and ocean surface temperature. The data is presented as temperature anomalies, which are the difference between the temperature of a given year and the average temperature from a reference period. -
Monthly Sunspot Dataset - This dataset includes a monthly count of sunspots from 1749 to 2018 (269 years). Sunspots are colder areas of the sun's surface created by huge variations in the magnetic field of the sun. These variations in the sun's magnetic field can cause solar flares and coronal mass ejections, which can have significant effects on the Earth's atmosphere and climate. -
Ozone Level Detection Dataset - This dataset includes two ground ozone level datasets used to detect the ozone level in the atmosphere. It was gathered in Houston, Galveston, and Brazoria areas between 1998 - 2004 and includes measurements of ozone levels on an hourly basis, where one is the eight-hour peak set (eighthr.data) and the other is the one-hour peak set (onehr.data).
