AirPhoton Inc., fomed in 2012, is the U.S. division of GRASP-Earth. We design and manufacture instruments to measure airborne particulates and trace gases. Our instruments are built for field deployment but provide high end capabilities typically found in laboratory instruments. Typically our instruments are used to study particulate characteristics for air quality and human health, and/or climate applications. Our instruments are deployed globally by the SPARTAN Network, NASA’s MAIA mission and a host of research institutes. Our company founders are scientists who have been working in the area of particulate measurements since the early 90’s. We don’t just sell instruments, we provide expertise in the how, why and where of particulate and gas measurements.

In the summer of 2022 AirPhoton merged with GRASP-SAS, forming GRASP-Earth. GRASP-SAS has developed a data platform which is used to create aerosol, cloud and surface property data products for satellite sensors. It is widely used by several space agencies in Europe and operational product for missions such as Sentinel-4, CO2M or 3MI. Our goal for GRASP-Earth is to push the boundaries of instrument capabilities by integrating space and ground observations along with models to advance our monitoring and understanding of Earth’s atmosphere. We use GRASP with our in-situ optical instruments to allow us to maximize their information content and to create advanced products.

We are using GRASP in innovative new ways to synergistically combine data from various instruments to create data products which go beyond current offerings. These include: In-situ instruments with satellite data; satellite data from multiple platforms; and data from different types of in-situ instruments. Our instruments have unique features that our competitors do not offer and which you will see on the following section. If you have a question or a suggestion for an application or a new instrument please reach out. Innovation is a collaborative process that is enriched by many minds.
