A new fire emissions inventory, providing publicly available data on trace gases and aerosols from global fires for the years 2002 through 2021, add improvements to previous inventory.

For over 20 years, a fleet of almost 4,000 Argo floats have measured ocean temperature and salinity across the globe. The eventual plan calls for floats to be evenly spaced across the global oceans, but a new study examines whether uniform spacing is the most effective float configuration.

Concern over the ongoing marine heat wave across South Florida and the surrounding region led NOAA scientists to check on Cheeca Rocks, an inshore reef within the Florida Keys National Marine Sanctuary. Scientists visited on July 31 and August 1, 2023, and what they found was bleak.

How much rain and snow usually fall this month? Based on daily observations from 1991-2020, colors on the map show long-term average precipitation totals in 5x5 km grid cells for the month displayed. The darker the color, the higher the total precipitation.

The 120-day Tropical Pacific Observing System (TPOS) 2023 Saildrone Mission officially began on June 22, 2023, just after the official start of what experts suggest may be a strong El Niño.

Registration is open for the Earth's Radiation Budget Science Meeting. The meeting will be held at NCAR/UCAR's Center Green Campus in Boulder, Colorado, from November 6 to November 8, 2023.

Phytoplankton strongly influence ocean carbon storage, so scientists want to understand what affects these tiny organisms. A new study identifies solar radiation as the most important driver of phytoplankton biomass.

The August temperature outlook favors well above-average temperatures across the southern tier of the country. Above-average precipitation is favored across the middle of the country.

Experts are deploying numerous measures to protect, relocate, and “bank” live fragments of coral to help Florida’s Coral Reef survive a heat crisis that may last for months.

The swings between El Niño and La Niña have been bigger in recent decades than earlier ones. Our guest blogger covers new research pointing the finger at human-caused climate change.
