Where can I find IceCube data releases and real-time alerts?

Updated

IceCube's data releases and real-time alerts are reachable from the main site navigation at icecube.wisc.edu. Use Data Releases if you want archived, citable datasets for analysis; use Real-Time Alerts if you want notifications of neutrino events as they are detected. Both are aimed at researchers and the interested public, and neither requires a described login or payment on the pages referenced here.

Data Releases

The Data Releases entry in the site navigation is the starting point for IceCube's published datasets. This is the right section when you need:

  • Archived neutrino data that has been prepared for external use
  • A citable reference for a specific release
  • A stable location to return to when reproducing or comparing analyses

If you are writing a paper, building a analysis pipeline, or checking what IceCube has already made public, start here rather than in the news or outreach sections.

Real-Time Alerts

The Real-Time Alerts section covers neutrino events flagged as they happen. Choose this when your goal is:

  • Following high-energy neutrino candidates shortly after detection
  • Cross-checking alerts against other observatories' notices
  • Monitoring activity rather than downloading a fixed dataset

Real-time alerts and data releases serve different purposes: alerts are time-sensitive and event-driven, while releases are curated and versioned. If you need reproducibility, use releases; if you need timeliness, use alerts.

Related entry points on the same site

The site groups several other resources that give context to the data:

Section What it gives you
Research Highlights Summaries of IceCube science across neutrino physics, glaciology, and dark matter
Publications The collaboration's scientific papers
Beyond IceCube Broader scientific context around the observatory's work
News Announcements, including detector and upgrade updates

A recent example of the kind of result these sections point to: IceCube reported a search for the source of KM3NeT's record-breaking event, and the site also notes a renewed NSF cooperative agreement for operating and maintaining the observatory for 2026–2031.

How to choose

  • Need data to analyze or cite → Data Releases
  • Need to know about events now → Real-Time Alerts
  • Need background or results → Research Highlights, Publications, Beyond IceCube

All of these are linked from the top-level navigation on icecube.wisc.edu, so you can move between them without leaving the site.
