The interactive web page contains supplementary information to Acoustic signals of a meteoroid recorded on a large-N seismic network and fibre optic cables. It aggregates the probabilistic trajectory inversion results for the observed meteor explosion above south Iceland on July 2, 2022. These inversion results of a hypersonic moving source model (MSM) are based on travel time picks of the first arrival (A1) and the last arrival (LA), both, in homogeneous and layered atmospheric model. Additionally we present the inversion results of a simple point source model (PSM) based on the arrival times of A1 and LA.
This data publication comprises (1) a one-year data set of ground-based GPS raw signal observations (inphase and quadphase C/A code correlation sums, NCO phases, pseudoranges) aiming at geometric elevation angles below +2°, (2) the "OpenGPS" receiver software and (3) MATLAB source code to access the raw data files.
(1) ground-based GPS raw signal observations:
Within the "GLESER" measurement campaign 2581 validated setting events were recorded by the "OpenGPS" open-loop tracking receiver at an observation site located at 52.3808°N, 13.0642°E (Potsdam, Germany) between January and December 2014. The instrument provided on average 8.3 observations per day with three data gaps (29 January to 1 February, 29–31 August and 18–22 December 2014) caused by hardware or software problems, operator errors or other technical reasons. Between 15 July and 6 September the "OpenGPS" receiver malfunctioned due to an operator error and 437 observations from that time period are removed from the data set leaving 2581 low-elevation events.
Raw data files are stored in compressed tar archives each covering one week of observations. For more information see document "readme-gleser-dataset.pdf".
(2) "OpenGPS" receiver software:
The compressed tar archive "gleser-OpenGPS-src.tar.gz" includes (C code) sources of the OpenGPS receiver hardware. The receiver software is designed for "OpenSourceGPS"-compatible hardware (Kelley, 2002) and Linux operating system. During the 2014 campaign kernel version 2.6.32 (OpenSUSE version 11.3) with real-time extension module RTAI (RealTime Application Interface for Linux) version 3.8.1 was used. For more information see the document "readme-gleser-OpenGPS.pdf".
(3) MATLAB source code:
The compressed tar archive "gleser-readdata-src.tar.gz" contains a MATLAB function file that may be used to access the raw data files. For more information see the document "readme-gleser-readdata.pdf".
