### Where can I find high-resolution, historic weather data for urban areas (like ERA5 but higher spatial resolution)?

Pretty much what the title says. For my work I need historic (at least starting 2010), atmospheric weather data (mostly temperature at 2m, wind velocity and direction, humidity respectively dewpoint, ...
