An Update on Radiation Data from Japan
It’s time to give a brief update on my efforts to make radiation data provided by the Japanese administration more accessible.
The good news: I can now offer you a way more complete raw data download with higher data quality. Data now goes back until March 1. This means, the complete development of the nuclear crisis since the earth quake and Tsunami is covered.
Please see the Japan Radiation Open Data page for details on the download.
Some bad facts remain. Fukushima and Miyagi prefectures still don’t report values to the SPEEDI system (which is the source of the data). Their values are lacking since 2011-03-11 05:40 UTC. And Ishikawa prefecture hasn’t contributed values since yesterday.
In the meantime, people have started using the data available. The example below is a screenshot from a Japan Radiation Map created by Geir Endahl.
Eron Villarreal has contributed a data dashboard using Tableau Software.
Please comment to let others know what you are doing with the radiation data.
Update: I have done a draft animation to visualize the “burst” effects in Ibaraki around March 14.
