Environment/Climate Portal - Overview

Through its partnerships with industry, government, and academia, NIST is helping to advance measurements and tools for environmental science, for example by calibrating the sensors of climate-mapping satellites and detecting ever more minute quantities of toxins and pollutants in our air, soil, water, and blood.
