We constructed a dataset of offshore oil and gas platforms to improve knowledge of human activities at sea and their environmental impacts. Using satellite images from the Sentinel-1 and Sentinel-2 missions, we identified over 5000 platforms in six major offshore basins between 2017 and 2023 and recorded their locations and status. This open dataset extends existing records and supports environmental monitoring, offshore infrastructure management, and planning of mitigation strategies.

Routine monitoring of industrial emissions is vital to understand the location, frequency, and intensity of methane emissions. We used satellite and aircraft measurements to understand methane emissions from Madrid across various scales and sectors. Using a range of methods, we identify a clear gap between top-down and bottom-up approaches, discuss challenges associated with satellite interpretation, connect emissions to on-site practices, and make recommendations towards operational use.

Satellites that observe Earth must agree with each other so their data can be combined into long, reliable records. We compared two major missions, Landsat-9 and Sentinel-2, using a third satellite, EMIT, as a bridge. By matching images of the same locations worldwide, we found the two missions agree to within a few percent across most spectral bands. This approach avoids problems that affect direct comparisons and can be applied to future, more accurate calibration satellites.

Methane plumes can be detected with several instruments from space at a high spatial resolution nowadays. We see a ground projection of these methane plumes from the satellites that, similarly to clouds or buildings, are distorted depending on the observation and illumination angle. Here we highlight this issue and propose a methodology to account for it using simulations that could enhance current and upcoming retrieval and quantification algorithms.

Detection of methane point source emissions with satellite-based imaging spectrometers is assessed in offshore areas. After integrating simulations into data from 2 different satellite missions, we extract the probability of detection. We compare our results with real plumes, which shows the consistency of the models. Detection and monitoring efforts can be optimized by filtering data based on these results, reducing unnecessary searches and increasing the action taken on these emissions.

Methane is a potent greenhouse gas that has been responsible for around 25 % of global warming since the industrial revolution. Consequently identifying and mitigating methane emissions comprise an important step in combating the climate crisis. We develop a new deep learning model to automatically detect methane plumes from satellite images and demonstrate that this can be applied to monitor large methane emissions resulting from the oil and gas industry.

Here we present a novel model of global photosynthesis, ChloFluo, which uses spaceborne chlorophyll fluorescence to estimate the amount of photosynthetically active radiation absorbed by chlorophyll. Potential uses of our model are to advance our understanding of the timing and magnitude of photosynthesis, its effect on atmospheric carbon dioxide fluxes, and vegetation response to climate events and change.

Using two machine learning models, which were trained on TROPOMI methane satellite data, we detect 2974 methane plumes, so-called super-emitters, in 2021. We detect methane emissions globally related to urban areas or landfills, coal mining, and oil and gas production. Using our monitoring system, we identify 94 regions with frequent emissions. For 12 locations, we target high-resolution satellite instruments to enlarge and identify the exact infrastructure responsible for the emissions.

We present a methane flux rate retrieval methodology using the Sentinel-2 mission, validating the algorithm for different scenes and plumes. The detection limit is 1000–2000 kg h−1 for homogeneous scenes and temporally invariant surfaces and above 5000 kg h−1 for heterogeneous ones. Dominant quantification errors are wind-related or plume mask-related. For heterogeneous scenes, the surface structure underlying the methane plume can become a dominant source of uncertainty.

We review the capability of satellite observations of atmospheric methane to quantify methane emissions on all scales. We cover retrieval methods, precision requirements, inverse methods for inferring emissions, source detection thresholds, and observations of system completeness. We show that current instruments already enable quantification of regional and national emissions including contributions from large point sources. Coverage and resolution will increase significantly in coming years.

This study seeks to present the as-yet-unknown potential use of WorldView-3 for the mapping of methane point source emissions. The proposed retrieval methodology is based on the idea that the spectral channels not affected by methane can be used to predict the methane-affected band through regression analysis. The results show the precise location of 26 independent point emissions over different methane hotspot regions worldwide, which prove the game-changing potential that this mission entails.

Short summary
Sun-induced chlorophyll fluorescence (SIF) is an electromagnetic signal emitted by plants in the red and far-red parts of the spectrum. It has a functional link to photosynthesis and can be measured by satellite instruments, which makes it an important variable for the remote monitoring of the photosynthetic activity of vegetation ecosystems around the world. In this contribution we present a SIF dataset derived from the new Sentinel-5P TROPOMI missions.

Short summary
Methane emissions can be identified using remote sensing, but surface-related structures disturb detection. In this work, a variation of the matched filter method that exploits a large fraction of the near-infrared range (1000–2500 nm) is applied. In comparison to the raw matched filter, it reduces background noise and strongly attenuates the surface-related artifacts, which leads to a greater detection capability. We propose this variation as a standard methodology for methane detection.
