VOLCANOMS

Volcanic Anomalies Monitoring System (VOLCANOMS) is a thermal anomalies detection system of volcanic origin based on the analysis of satellite images from the Landsat system (Land Remote Sensing Satellite), specifically images specifically images Landsat of kind TM (Thematic Mapper), ETM+ (Enhanced Thematic Mapper Plus) and OLI (Operational Land Imager). The technical characteristics of the images can be obtained from the official website: http://landsat.usgs.gov/

VOLCANOMS is based in the Three Bands Three Components method (MTBTC; Rothery et al 1988; Harris et al 1999a; Harris et al 1999b), analysis of thermal images through the Blackett's method (2014) and improvements to MTBTC made by Gonzalez et al (2015).

VOLCANOMS produces various products and data related to:

A set of images corresponding to the infrared and short wave bands (SWIR; band 5 and 7 for Landsat TM and ETM+, band 6 and 7 for Landsat OLI), and thermal infrared bands (TIR; band 6 for Landsat TM and ETM+, and band 10 for Landsat 10), uncorrected and corrected for atmospheric and solar effects.

Images in combination RGB (542, 742 and 754 for Landsat TM and ETM+; 653, 753 and 765 for Landsat OLI).

Datasets that includes the area the the thermal anomalies, thermal radancy for the bands, SWIR and TIR, effective thermal temperature, heat and mass fluxes. Additionally, brightness temperature are presented and the radiant flux obtained for the bands TIR.
