The following data have been acquired by the ASTER instrument on the NASA Terra satellite. The sensor has been targeted in an urgent request mode to collect data of Eyjafjallajokull Volcano at every possible overpass, both day and night. ASTER acquires data in the visible/near infrared (VNIR) [0.56 - 0.81 microns] and in the thermal infrared (TIR) [8.29 - 11.32 microns] regions during day time overpasses and in the TIR at night. The VNIR images are at 15 m/pixel resolution and the TIR are 90 m/pixel (each image covers approximately 60 km by 60 km). All data have been processed to either brightness temperature in Celsius, VNIR reflectance, or plume composition. Composition of the plume is derived from a spectral deconvolution approach using laboratory TIR spectra. The ability to acquire high resolution data in the TIR and VNIR of the proximal region of the vent(s) allows for a more precise determination of thermal output, monitoring of potentially new temperature anomalies, and determination of the products in the plume.
