Wildflower Bloom Observations: The Global Learning and Observations to Benefit the Environment (GLOBE) Observer App allows citizens to record land cover observations like flowering events, which help scientists detect and validate large-scale blooms in satellite imagery.

NASA Takes to the Air to Study Wildflowers: News article on how NASA is utilizing advanced imaging spectrometers mounted on aircraft to monitor wildflower blooms, capturing data across hundreds of light wavelengths to track seasonal changes in plant life.

Example of California superblooms: News article on how California's wildflower superblooms have become so expansive, following record winter precipitation, that they are now visible from space and captured in satellite and aerial images by NASA, the European Space Agency (ESA), Planet Labs, and Maxar.

NASA Worldview Superbloom Visualizations:

California superbloom images: Satellite images from NASA’s Landsat 8 and 9 and ESA’s Sentinel-2 missions captured a superbloom (yellowish areas) around the Pine Flat Lake and along the Kings River, in the Sierra Nevada foothills of eastern Fresno County, California.

Comparison between two superbloom seasons I: Swipe comparison of two Landsat 8 and 9 images showing changes between two Superbloom seasons, 2020 vs 2023, in the Antelope Valley California Poppy Preserve, California.

Comparison between two superbloom seasons II: Swipe comparison of two Landsat 8 and 9 images showing changes between two Superbloom seasons, 2020 vs 2023, in the Carrizo Plain National Monument, California.

"Deciphering the spectra of flowers to map landscape-scale blooming dynamics," by Y. Angel, A. Raiho, D Kathuria, K. Chadwick, P. Brodrick, E. Lang, F. Ochoa, A Shiklomanov. Ecosphere. 2021. Explores how analyzing the spectral signatures of flowers can enhance our understanding of large-scale blooming patterns. By examining flower spectra, researchers aim to improve the monitoring and mapping of blooming dynamics across landscapes, providing valuable insights into ecological processes and environmental changes.

Canadian Space Agency (CSA)

Radarsat Constellation Mission (RCM) - Data Portal: The RADARSAT Constellation Mission (RCM) is Canada's new generation of Earth observation satellites. The RCM includes a trio of Earth observation satellites, capable of scanning Earth day or night and in any weather conditions. The RCM is designed to provide effective solutions in three main areas: Maritime surveillance (ice, surface wind, oil pollution and ship monitoring); Disaster management (mitigation, warning, response and recovery); and Ecosystem monitoring (agriculture, wetlands, forestry and coastal change monitoring).

RADARSAT 1 - Data Portal: Launched in November 1995, RADARSAT-1 provided Canada and the world with an operational radar satellite system capable of timely delivery of large amounts of data. Equipped with a powerful synthetic aperture radar (SAR) instrument, it acquired images of the Earth day or night, in all weather and through cloud cover, smoke and haze. All data products in the Canadian RADARSAT-1 archive have been released under an open license

Brazilian National Institute for Space Exploration (INPE) Catalogue: INPE's images Catalog provides a database with thousands of images generated by more than 16 satellites, with resolutions varying from 2 meters to 64 meters. Cameras include Multispectral, wide field imagers, panchromatic, among others. All images are available to the public in the linked platform, which integrates search tools for filtering the database.
