Our atmosphere protects us from a hostile space radiation environment comprising high energy particles of solar and intergalactic origin. Solar radiation is significant during unpredictable and short lived solar flares and coronal mass ejections (CMEs); however, galactic cosmic radiation (GCR) is omnipresent. The GCR intensity varies with latitude, longitude, and time due to effects of solar activity on the interplanetary magnetic field, as well as the Earth's magnetic field. Space radiation collides with gases in the atmosphere, leading to a complex shower of high energy radiation, the intensity and composition of which varies spatially and temporally. Excessive exposure to radiation can damage DNA and lead to long-term health effects such as an increased risk of cancer.
Resulting radiation levels at commercial aircraft altitudes are greater than at sea level. Aircrew are classified as radiation workers in some countries; however, planning to limit their exposure, and monitoring, is generally lacking. Both real-time measurements and predictive models of radiation in the atmosphere are important to mitigate the radiation risk to crew.
We host a RESTful API to models of cosmic ray induced ionising radiation in the atmosphere.
The CARI7 and PARMA endpoints use models developed by the US Federal Aviation Administration and the Japan Atomic Energy Agency to calculate cosmic radiation doses at a point.
The Route Dose API calculates the same quantities along a great circle route between two airports using CARI7.

The gravitational field of the earth is non-uniform. The geoid is the shape the
ocean surface would take if only gravity and the rotation of the Earth
were considered. The geoid is the surface that defines zero elevation.
The geoid height is the difference between an ideal reference ellipsoid and the geoid.
The gravity anomaly is the difference between the acceleration due to gravity on the Earth's surface and the value calculated assuming the reference ellipsoid.
The official Earth Gravitational Model EGM2008 was developed and released to the public by the National Geospatial-Intelligence Agency (NGA).
Our EGM2008 API provides on-demand access to the EGM2008 model, as implemented by the open-source GeographicLib Gravity library.

Space has a hostile radiation environment that increases the risk of cancers in humans and malfunctions in spacecraft electronics. The types of space radiation of primary concern are:
- Galactic Cosmic Rays from outside our solar system generated by supernovae and other phenomena;
- Solar Energetic Particles produced by the Sun during intense and sporadic bursts of activity; and
- Trapped Radiation: energetic particles confined by Earth's magnetic field, usually comprising an inner belt of mostly high energy protons and an outer belt dominated by lower energy electrons and plasma.
