London's transport authority uses data sharing principles to solve city-wide challenges like air quality and safety, explains former head of open innovation at Transport for London, Rikesh Shah.

Transport for London (TfL) makes much of its operational data available via open source. Beginning 10 years ago, this approach has allowed companies – including tech start-ups – to develop apps that offer real-time travel advice, transforming passenger journeys, and boosting London’s economy by £130 million a year.

To assist the science community in conducting studies of climate change impacts at local to regional scales, NASA created the NASA Earth Exchange (NEX) Global Daily Downscaled Projections (GDDP) dataset, or NEX-GDDP-CMIP6. This dataset is expected to enhance public understanding of possible future climate patterns at the spatial scale of individual towns, cities, and watersheds. It provides a set of global, high resolution, bias-corrected climate change projections that can be used to evaluate climate change impacts on processes that are sensitive to finer-scale climate gradients and the effects of local topography on climate conditions. As part of the Amazon Sustainability Data Initiative (ASDI), this dataset is available at no cost on the Registry of Open Data.
