Recently, American meteorologist Vernon Dvorak, credited with having developed ADT in the 1970s,  passed away at the age of 100.

 What is ADT?

The Advanced Dvorak Technique (ADT) utilizes longwave-infrared, temperature measurements from geostationary satellites to estimate tropical cyclone (TC) intensity. 

  • During day time, images in the visible spectrum were used while at night, the ocean would be observed using infrared images.
