16 Years of GPS Space Weather Data Made Publicly Available (sciencemag.org) 52

"It's not often that a scientific discipline gains a 23-satellite constellation overnight," reports Science magazine, describing 16 years worth of radiation measurements from GPS satellites finally released by Los Alamos National Lab. "Although billions of people globally use data from GPS satellites, they remain U.S. military assets." Scientists have long sought the data generated by sensors used to monitor the status of the satellites, which operate in the heavy radiation of medium-Earth orbit and can be vulnerable to solar storms. But few have been allowed to tap this resource... That attitude changed in October 2016, when the outgoing Obama administration issued an executive order aimed at preparing the country for extreme space weather. Such bursts in charged particles, originating in a solar flare or coronal mass ejection, could disable the electrical power grid or divert flights away from the Arctic, where radiation exposure is heightened. The GPS data, which dates from December 2000, fill a hole in studies of space weather, the complex interplay of Earth's magnetic field with bombarding radiation from cosmic rays and the sun.

    Like how much weather is there in space?

    • underwater has its own kind of "weather" so why wouldn't above the atmosphere have "weather" (used as shorthand for a measure of the ambient conditions in X).

  • It takes a while to falsify the data.

      It takes a while to falsify the data.

      They also covered up the fact that the Bowling Green Massacre of 2011 was a false flag operation and thousands of Muslims in New Jersey were in the streets cheering.

        Well I for one, will not stand by while the countless familie killed by these evil people are not helped.

        I've started a GoFundMe and Patreon page to collect money to help these poor people. And if they don't claim it..........

    They present the data as 23 folders with over 100 ASCII at 5 MBs each. Downloading each one by one is annoying but not a show stopper, but why not compress?

    I downloaded one of the files and used 7Zip to throw it into a Z archive. The size went from 5 MB down to 500 KB. I uncompressed to make sure it wasn't a fluke but was 100% accurate.

    Shouldn't we expect a little more from the country's best and brightest? I mean, come on...

      http compresses anyway.

    • by mmell ( 832646 )
      Why compress? HTTP can already compress the data stream and reliably decompress it on the receiving end. If they compressed it, they'd have to hear from everyone that had difficulty decompressing the data (because of the compression algorithm chosen, the configuration of that algorithm, possible incompatibility caused by people using old or broken decompression clients, etc.).

      They made the data available. Now that you've downloaded one of the files (for some reason other than to load down their server a

      • As I mentioned above, there is no HTTP compression and it's over 8000 files at over 60 GB uncompressed. Had they compressed it, I am certain it would be less than 1 GB based off the tests I mentioned.

        Imagine all the bandwidth being wasted. I think it's incredulous to release a huge treasure trove of data this big and not think of compressing.
        • Imagine all the bandwidth being wasted. I think it's incredulous to release a huge treasure trove of data this big and not think of compressing.

          Good heavens - if it is such a hardship, don't download it.

          Regardless, I'm not certain if it is a good idea to download this or not. It's probably NASA trying to get as much of their data out there before they are cleansed of scientists who do not straighten up and fly right. Which is apparently what is happening with the AGW data as well. This stuff might be illegal soon.

          • Which is why I want to download it and archive it. If there is a threat that scientific data is going to be attacked and purged, we should all be saving a copy just in case.
    • I downloaded the entire dataset folder and compressed into a two-part ZIP for easy download and/or archiving to DVD.

      Files are available on Amazon S3 here:

      GPS+Energetic+Charged+Particle+2016-12-08+63GBs.zip.001 [amazonaws.com]

      GPS+Energetic+Charged+Particle+2016-12-08+63GBs.zip.002 [amazonaws.com]

      Keep in mind that the total folder is over 63 GBs and 8000 files.
      • Sure you did.

        How much do you want to wager that it now is ten thousand copies of Goats.exe?

        • You would lose the wager. Because the files are on my personal AWS account's S3 bucket and can be easily traced back to me by law enforcement if it has anything illegal or harming inside.

          I get the joke but the zips are a serious effort to help get the data shared. The original source took almost 6 hours to download fully because did they not compress or compact the files in any way. I'm just trying to save others interested that effort (and their bandwidth budgets for people with caps).

        And also available as a single xz-compressed tarfile: http://drevans.blog.enginehous... [enginehousebooks.com]. (This file is about 1.3 GB smaller than the sum of the two zip files.)

  • But what we could really use is the next 16 years of space weather.
