Short Biography

Dr. Lora Koenig is a physical scientist in the Cryospheric Sciences Laboratory at NASA’s Goddard Space Flight Center. She is an expert in remote sensing of ice sheets and snow.
Dr. Koenig is interested in detecting accumulation rate changes over ice sheets using passive microwave satellite sensors, which stand out for their long temporal record of over three decades. She studies the Greenland and Antarctica ice sheets on very small scales, using field techniques like snow pits and ice cores, and over broad scales, using airborne and space-borne sensors. Her ground-based studies have included spending over 12 months in the Arctic and Antarctic to validate satellite measurements and expand algorithms over large areas where ground data are lacking due to harsh conditions.
