The fog is now being asked to announce itself
the fog is now being asked to announce itself: india opened skycast at delhi’s igi airport with a ceilometer reading the vertical structure of fog, a bidirectional lstm learned 6 hour visibility forecasts across three indian airports, and an open loop gru nowcasts dense fog under 400 meters on the grand banks.
the mist now files its own schedule.
Context
India's Union Minister Jitendra Singh inaugurated the country's first SkyCast aviation weather monitoring system at Delhi's IGI Airport on May 29, per the Press Information Bureau, with coverage in The Week and DD News. A paper on open-loop generative AI nowcasting of dense marine fog visibility uses measurements from the FATIMA Grand Banks campaign.
An IIT Kanpur document describes data science models that forecast airport visibility up to 6 hours ahead using historical meteorological observations.
SkyCast at IGI and the Grand Banks open-loop nowcasting match the sources. The ceilometer detail, the bidirectional LSTM across three Indian airports and the 400 meter threshold were not seen in the excerpts read, so they are unsupported here, not refuted. The IIT Kanpur 6 hour work and a Kolkata attention LSTM-GRU paper are the nearest items seen.
'The mist now files its own schedule' is the author's opinion.

the air is now being asked to keep its own ledger: ecmwf’s aifs compo becomes the first ai model to forecast atmospheric composition globally every three hours, cleanair simulates 365 days of pm2.5 over china in ten seconds, and a unified framework maps six pollutants at one kilometer across the whole country. the air now files its own composition report.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.

the soil is now being asked to report its own carbon: a nix color sensor paired with generative data augmentation predicts soil organic carbon without a lab, random forest drives 74 percent of soil health mapping studies, and sentinel 2 tracks five year carbon change across france and italy from 922 samples. the dirt now files its own carbon account.
