Data specification

TIRNet stations acquired IR data from different IR cameras in time.

NEC TS7302 camera

The older IR camera is the NEC TS7302 (resolution = 320x240px), operative since 2004 at Solfatara1 and Vesuvius stations.

The final product is a TXT temperature matrix file obtained after conversion of NEC SIT proprietary file. In the download page are available compressed files (rar) for the two stations, containing one TXT file every day, selected between the three scenes acquired at nigh-time and which has passed quality control. The time-series could be not continuous due to bad weather conditions at acquisition time or technical malfunctions.

FLIR SC325 - FLIR A40

These cameras were operative at Solfatara1 (SC325) and Vesuvio (A40) stations in the years 2014-2016 and 2011-2019 respectively . Resolution of frames acquired by FLIR SC325 and A40 is 320x240. IR frames were corrected during acquisition by using values of air temperature, air humidity and sensor-target distance.

The final product is a CSV temperature matrix file obtained after conversion of FLIR radiometric JPEG proprietary file. In the download page are available for each station: 1) a compressed file (rar) containing CSV files which has passed quality control between the three scenes acquired at nigh-time every day; 2) a compressed file (rara) containing the FLIR radiometric JPEG. The time-series could be not continuous due to bad weather conditions at acquisition time or technical malfunctions.

FLIR SC645/655

These cameras are currently operative in all the 7 stations of TIRNet surveillance network. Resolution of frames is 640x480. IR frames were corrected during acquisition by using values of air temperature, air humidity and sensor-target distance.
