    “Highlights:
    • A novel method for detecting geothermal components from solar energy dominated LST.
    • Using LST time series to eliminate temporal variant solar energy input.
    • Uncertainty in anomaly identification quantified by probability measure.
    • Capable of revealing LST anomalies caused by geothermal, anthropogenic and surface processes..."

  2. RT by @CopernicusEU: The latest #eruption in #Iceland has produced the largest #volcanic SO₂ cloud measured to date in the 2023-24 #Reykjanes Fires, consistent with reports that it is the most intense episode so far.
    Data: @CopernicusEU #Sentinel5P #TROPOMI.

    "HIGHLIGHTS:
    • [They] mapped channels and fossae within the volcanic plains east of Olympus Mons.
    • Late Amazonian channels east of Olympus Mons formed by eruptions of lava or water.
    • Fossae morphologies correspond to episodes of magmatic dike and sill emplacement.
    • Loading of Olympus Mons may control magmatic ascent processes and eruption types..."

  8. One of my favorite tools to use in the UO #Coffee Lab is the Malvern particle size analyzer which can characterize particles with sizes in the range of 0.1-2000 μm. I've used one like this extensively to measure #volcanic ash grains. Today, however, I am working with a (quite bad) medium roast coffee, exploring controls on particle agglutination. Turns out the processes that control volcanic ash aggregation and coffee clumping are pretty similar (i.e. #water and #electrostatics). #espresso
