Quickstart

Here, we show an example of loading data from CDAWeb using Speasy.jl and visualizing it with SpacePhysicsMakie.jl. For additional approaches to retrieving data, see the Julia Space Physics Tutorials. You can also refer to the Data page for a detailed explanation of supported data formats and retrieval methods.

Get data with Speasy

Speasy.jl provides functions to load data from main Space Physics WebServices (CDA,SSC,AMDA,..).

It could be installed using using Pkg; Pkg.add("Speasy").

using Speasy
using CairoMakie, SpacePhysicsMakie

# da = get_data("amda/imf", "2016-6-2", "2016-6-5")
data = Speasy.get_data("cda/OMNI_HRO_1MIN/Pressure", "2016-6-2", "2016-6-3"; sanitize=true)
