Data Explorer is an web application for HAPI (Heliophysics Data Application Programmer's Interface) servers. HAPI is a specification for time series download and streaming.

(Another web application for HAPI servers is the KNMI Space Weather Timeline Viewer, which allows one to build interactive stack plots of data from HAPI servers.)

When data are available from a HAPI server, there is no need to download data files and write custom file reader programs or to install custom software packages to access data for each data provider. Using a HAPI client library, data can be loaded into an array using a single command in cURL / IDL / IDL SPEDAS / Javascript / MATLAB / Python / Python SPEDAS / Python Kamodo / Wget.

Space Weather-related data are available through this interface and HAPI software from AMDA , CAA , CCMC , CDAWeb, DAS2, INTERMAGNET, KNMI, LISIRD, SSCWeb, and ViRES.

HAPI servers are available from the Data Explorer.

• Use this interface to
  • generate a HAPI URL to download data,
  • plot data, and
  • generate scripts (with install instructions) that read and plot the selected parameter using HAPI clients for cURL / IDL / IDL SPEDAS / Javascript / MATLAB / Python / Python SPEDAS / Python Kamodo / Wget. Example scripts can be created using links in Example Queries or by selecting Return: script in the drop-down menu after selecting a server, dataset, parameters, and time range.
• Begin by selecting a HAPI-enabled data server in the drop-down menu or selecting Example Queries above.
