SCISAT, also known as the Atmospheric Chemistry Experiment (ACE), is a Canadian Space Agency small satellite mission for remote sensing of the Earth's atmosphere using solar occultation. The satellite was launched on 12 August 2003 and continues to function perfectly. The primary mission goal is to improve our understanding of the chemical and dynamical processes that control the distribution of ozone in the stratosphere and upper troposphere, particularly in the Arctic. The high precision and accuracy of solar occultation makes SCISAT useful for monitoring changes in atmospheric composition and the validation of other satellite instruments. The satellite carries two instruments. A high resolution (0.02 cm-¹) infrared Fourier transform spectrometer (FTS) operating from 2 to 13 microns (750-4400 cm-¹) is measuring the vertical distribution of trace gases, particles and temperature. This provides vertical profiles of atmospheric constituents including essentially all of the major species associated with ozone chemistry. Aerosols and clouds are monitored using the extinction of solar radiation at 1.02 and 0.525 microns as measured by two filtered imagers. The vertical resolution of the FTS is about 3-4 km from the cloud tops up to about 150 km. Peter Bernath of the University of Waterloo is the principal investigator. A dual optical spectrograph called MAESTRO (Measurement of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation) covers the 400-1030 nm spectral region and measures primarily ozone, nitrogen dioxide and aerosol/cloud extinction. It has a vertical resolution of about 1-2 km. Tom McElroy of Environment and Climate Change Canada is the principal investigator. ACE data are freely available from the University of Waterloo website. SCISAT was designated an ESA Third Party Mission in 2005. ACE data are freely available through an ESA portal.
Including data and software from CrystalEye is this a open-access collection of crystal structures of organic, inorganic, metal-organic compounds and minerals, excluding biopolymers. At present, this is the most comprehensive open resource for small molecule structures, freely available to all scientists in Lithuania and worldwide. Including data and software from CrystalEye, developed by Nick Day at the department of Chemistry, the University of Cambridge under supervision of Peter Murray-Rust.
The Online Data Portal (ODP) is an evolving project to support collaborative river restoration projects, such as the TRRP. The goal is to provide a centralized clearing house of documents and data for program partners, stakeholders, and the public. The functionality and data holdings will continue to be expanded over the next few years. The ability to store Data Packages is new as of Fall 2011 and holdings should expand substantially in the months afterward. A project to scan many older documents also began in December 2011. Simple time-series datasets have long been stored in the ODP, but holdings of these data are likely to increase as TRRP implements an upcoming Data Management and Utility Plan. Major upgrades to the Interactive Map are expected to start in winter and spring of 2012. The long term vision is that many data resources will be accessible both by text searches and via the Interactive Map. The ODP will be available for use by other river restoration programs. ODP is followed by TRRP DataPort.
