status = status of the signal (bit 1 = polarity negative, bit 2 = polarity positive, bit 3 = signal is used for the computation)Įach variable of the stations file may have the following members.

alt = altitude of the detector in meter.

lon = longitude of the detector in degree (decimal).

lat = latitude of the detector in degree (decimal).

time = time difference to the time of the lightning strike in nano seconds.

sta = station that has received the signal.

mcg = maximal circular gap in degree (for example, 210 degree = the detectors are in a sector of 150 degree from the point of view of the impact position), optionalĮach signal of the sig array may have the following members.

mds = maximal deviation span in nano seconds.

line of the data files contains one JSON codes variable.Įach variable of the lightning strike files may have the following members.sig=0/1 provides entries excluding/including the information of the signals involved (default = 0)Įxample: The follwing url provides the last 10 entries from the last 1000000 entries with a longitude between -10.0° and 40.0°, a latitude between 70.0° and 20.0°, and without the information about the signals involved.south=lat provides only entries with a latitude of at least lat (default = -90).north=lat provides only entries with a latitude of at most lat (default = 90).east=lon provides only entries with longitude of at most lon (default = 180).west=lon provides only entries with a longitude of at least lon (default = -180).time=t provides the latest entries after time stamp t (given as UTC Nano Epoch Seconds).numer=x provides the last x entries (default = 100).

The parameters of the script have the following meaning. returned records are sorted time descending.To keep the transfer rate as high as possible, the data is not read from the disk but from the main memory. It considers the last 100000 entries (with signals involved) / 1000000 entries (without signals involved). The last strike data entries from all regions together up to the current time can also be accessed via the following url. You need to check whether the file is available in gzip format as 'XX.json.gz' or in simple text format as 'XX.json'. lightning data files and the stations file are updated every minute.Informations about all stations can be found in the file the lightning stike data for Region 1 (Europe) of 1'st August 2013 between 10:30 to 10:39.999999999.The strikes directories contain sub-directories named by the date and time of the lightning strikes in UTC times.Įach data file contains lightning strike information of 10 minutes.Įach line of these files consists of one variable coded in 'JSON' (JavaScript Object Notation).įiles older than 24 hours are only available as 'zgip' files. The current assignment of the directories to the regional areas is as follows:ĭirectory, computed region, server location The results are stored in the 'Strikes_xx' directories. The calculations of are carried out in several containers processed on different servers. They contain the following directories and files.

The 'Restricted' directory allows access to the raw data via special IP addresses. The directory 'Protected' allows access to the raw data using your loginname/password pair. One of these directories is a link to the other one. The raw data are located in the directories 'Protected' and 'Restricted'. This data is used by some older versions of the MyBlitzortung software. The directory 'Pulic' contains data that is not protected.
