Show HN: Probably the most comprehensive weather API currently available This was posted before but I'm quite pleased to share a major update for https://oikolab.com. We now have available seven decades of hourly weather data starting from 1950 for any location in the world, thanks to the recent publication of ERA5 reanalysis data from European Centre for Medium-Range Weather Forecasts (ECMWF). ERA5 is gap-free, gridded dataset generated using data assimilation method (https://ift.tt/2sZYnWj), similar to NWP models but with the benefit of hindsight. As far as we're aware of, we're the first weather data service provider to have this extensive range of coverage accessible via REST API, where one can quickly query time-series of weather parameters for any location in seconds rather than hours or days from the original source. Here are some stats: Coverage: Global, from 1950 to 10 days ahead Spatial Resolution: 0.25 deg x 0.25 deg (lat x lon) Temporal Resolution: Hourly Weather Parameters: ~30, including longwave/shortwave radiation, wetbulb temperature, windspeed at 100m, etc. (https://ift.tt/37bc4YZ) NetCDF/GRIB Data Size: ~100TB Data Sources: Historical (ERA5) - https://ift.tt/3oGvGKD Forecast (GFS) - https://ift.tt/1eg5Bxm Any feedback or comments would be much appreciated. Thanks! December 12, 2020 at 11:09AM
Show HN: Tape It, iOS recording app for musicians Hello HN, Over the last 15 months, two friends and I developed the music recording app we felt we wanted based on our own needs as musicians. It's called Tape It [1] and has just recently hit the Apple App Store [2]. We put a lot of effort into a good UX to help musicians really focus on playing their instrument instead of pretending to be a recording engineer. The app records in stereo on newer iPhones (although that's a premium feature; the free version only records in standard mono audio quality). I would be really grateful for advice from this community on how to best approach marketing. We had a great TechCrunch article covering our launch [3], and we posted it on various music websites. Turns out advertising on Google or Apple Search is a dark art, though. We have some good ideas for developing a good social media presence, but they will take time. Please hit us with feedback, opinions and advice that you think a young ind...
