These links provide a discussion of the aurora phenomena and tips for the best opportunities to view aurora at various locations around the world. It is the only way for most people to actually experience space weather. It is closely related to the ground induce currents that impact electric power transition.įor many people, the aurora is a beautiful nighttime phenomenon that is worth traveling to arctic regions just to observe. The aurora directly impacts HF radio communication and GPS/GNSS satellite navigation. The aurora is an indicator of the current geomagnetic storm conditions and provides situational awareness for a number of technologies. The aurora does not need to be directly overhead but can be observed from as much as a 1000 km away when the aurora is bright and if conditions are right. The aurora is not visible during daylight hours. Aurora can often be observed somewhere on Earth from just after sunset or just before sunrise. The sunlit side of Earth is indicated by the lighter blue of the ocean and the lighter color of the continents. The green ovals turn red when the aurora is forecasted to be more intense. The brightness and location of the aurora is typically shown as a green oval centered on Earth’s magnetic pole. The two maps show the North and South poles of Earth respectively. The forecast lead time is the time it takes for the solar wind to travel from the L1 observation point to Earth. This product is based on the OVATION model and provides a 30 to 90 minute forecast of the location and intensity of the aurora. Community gardens under parks jurisdiction are already protected from development under city rules, these officials argue, adding that not one garden in the GreenThumb program has closed in the past five years.Īs more frequent and intense storms brought about by climate change are predicted to hit New York, much more needs to be done at all levels to “rainproof the city,” said Amy Chester, managing director of Rebuild by Design, a nonprofit that recently released a report on the importance of “transforming the concrete jungle into a sponge.” This can be as simple as putting out barrels in backyards to collect rainwater that can be reused for watering plants or washing cars to more ambitious projects like retrofitting school and office buildings with green roofs.This is a short-term forecast of the location and intensity of the aurora. There is currently only one such designation in New York City, according to parks officials, and it is for an entire region: Jamaica Bay and it tributaries, tidal wetlands and adjacent areas. īut not everyone agrees that community gardens should be labeled critical environmental areas. They “are a small, but mighty resource in our portfolio of storm water management efforts across the city,” said Jennifer Greenfeld, the deputy parks commissioner for environment and planning. Figueroa said of the expedition’s findings.Ĭity parks officials - who oversee the majority of community gardens through their GreenThumb program - acknowledge that the gardens are a vital part of New York’s green infrastructure. “Wherever there were raised planting beds, composting and trees, that significantly contributed to the garden’s capacity to absorb and retain water,” Mr. Figueroa dispatched a half-dozen graduate students to community gardens across the city in 2019 to conduct interviews and collect data. The campaign grew out of a student project at the Pratt Institute, where Raymond Figueroa Jr., the president of the New York City Community Garden Coalition is a faculty member. In an effort to protect community gardens from development, more than 70 groups have petitioned city officials to designate the green spaces as “critical environmental areas” under state law. Many have added rain gardens and bioswales (trenches with vegetation designed to absorb water), and collected water from sheds, gazebos, pergolas and even the rooftops of neighboring buildings with “rainwater harvesting systems” like the one installed at Mobilization for Change.Īn estimated 165 million gallons of storm water are diverted from the city’s streets and sewer system every year because of community gardens, according to Earthjustice, an environmental law nonprofit, which based that figure on a 2016 analysis published in a scientific journal.Īdvocates like Earthjustice are pushing for broader recognition of the gardens’ ability to divert rainwater, especially after last year’s Hurricane Ida unleashed flooding that killed New Yorkers trapped in basement apartments, paralyzed streets and neighborhoods, and poured into subway stations. Increasingly, they have also become neighborhood outposts in the city’s efforts to control flooding. New York’s network of more than 550 community gardens has long been a refuge for cramped apartment dwellers, offering space to grow fresh vegetables and soak up sun and fresh air.
