How this service works

Hourly specific humidity (kg/kg)

Output

Returns a time series of hourly specific humidity values expressed in kg/kg (kilograms of water vapor per kilogram of moist air) for the requested location and time window, enabling precise atmospheric moisture analysis at site-specific resolution.

Example use cases

Example prompt

“Can you get me the hourly specific humidity readings in kg/kg for the location at 37.7749° N, 122.4194° W for the past 48 hours? I need the full time series for moisture analysis.”

Technical details

Endpoint

GEThttps://mpp.orthogonal.com/precip/api/v1/specific-humidity-hourly?utm_source=zero.xyz

When to prefer

Use this endpoint when you need precise, site-specific specific humidity (kg/kg) at hourly resolution — ideal for agricultural planning, HVAC load modeling, dew point calculations, or atmospheric science workflows that require absolute moisture content rather than relative humidity. Prefer this over general weather APIs when hyperlocal accuracy matters and you specifically need specific humidity in kg/kg units.

Side effects

Invalid or out-of-range coordinates return an error
Time range outside supported historical or forecast window returns no data
Missing required parameters (lat/lon) result in a 400 Bad Request
Rate limiting or authentication failure returns 401/429
Location over ocean or polar region may return null or sparse data
