Julia Barsi calibrates instruments on Landsat satellites.
I use Landsat data alongside other satellite and field data to map where and when crops like wheat are growing, to analyze different management practices including when crops are planted and harvested, to assess crop health and to forecast end of season yields.
We’ve processed more than 224,000 Landsat images of the boreal forest, from 1984 through 2020, all to understand changes in tree-cover extent.
In my Ph.D. research at McGill University in Canada, I used Landsat data to map fire progressions for Canadian wildfires.
I use Landsat to explore wetland and aquatic ecosystem dynamics over time, studying how they may vary in a changing climate. Biotic and abiotic, everything on Earth has its own connection.
I use Landsat data as part of a joint U.S. Department of Agriculture/NASA effort to inventory all forest lands in interior Alaska.
I worked at Goddard Space Flight Center for 43 years. A great deal of my career was spent engaged in the Landsat program.
