DEVOTE scientists conducted eleven science flights in September and October 2011 to collect aerosol and cloud measurements. The Research Scanning Polarimeter (RSP) on a NASA UC-12 aircraft gathered data over ground sites and along satellite overpasses. These measurements were used to validate and improve retrieval algorithms for missions like CALIPSO and the ACE Decadal Survey.
NASA's DEVOTE project collected in-situ meteorological and navigational data onboard a UC-12 aircraft during eleven science flights in September and October 2011. The campaign aimed to validate and improve satellite data retrieval algorithms for missions like CALIPSO and ACE. Data collection is complete and includes measurements from the Applanix POSAV system.
Eleven science flights were conducted in September and October 2011 by NASA's DEVOTE project. The B-200 aircraft collected in-situ meteorological and navigational data using instruments including a NAV420 IMU and two Diode Laser Hygrometers. These measurements were used to validate and improve satellite data retrieval algorithms for missions like CALIPSO and ACE.
A subset of the MISR Level 2 Aerosol Product for the INTEX-B 2006 theme, containing aerosol optical depth and particle type with associated atmospheric data. The dataset is produced by the National Aeronautics and Space Administration (NASA). The metadata was last updated on March 13,我们发现了一个错误。该日期是未来的日期,这可能是输入错误。根据协议,我们不能使用无法追溯到输入的事实。因此,我们不能在摘要中提及这个日期。我们将重新撰写摘要,不包含该日期。
Between 1991 and 1995, in-water optical and biogeochemical measurements were collected in the Northeast Pacific, North Atlantic, Gulf of Mexico, and Arabian Sea. This dataset was used to develop the Bio-Optical Algorithm (BOA) and is provided by the National Aeronautics and Space Administration. The data is stored in BIN and ISO file formats.
Daily 5-minute temporal satellite swaths from the MODIS/Terra instrument, produced by NASA until its decommissioning on July 31, 2023. The data is used to identify fires, volcanoes, and other thermal anomalies, with each swath covering approximately 2,030 by 2,300 kilometers. This Version 6 product has been succeeded by Version 6.1.
Global Affairs Canada compiled a set of bilateral agreements between Canada and the United Kingdom. The collection covers areas including taxation, trade, customs cooperation, defense, nuclear collaboration, and social security. The information is archived and was last updated on the platform in March 2026.
A compilation of bilateral agreements between Canada and the Union of Soviet Socialist Republics (USSR) across areas including trade, economic cooperation, nuclear collaboration, defence, investment, taxation, and air transport. The set includes specific instruments such as a wheat trade agreement, a protocol on economic cooperation, two nuclear agreements, a commerce protocol, a military visits agreement, an investment promotion and protection agreement, a taxation agreement, and an exchange of notes amending an air transport agreement. This archived collection was published by Global Affairs Canada and reflects cooperation prior to the dissolution of the Soviet Union.
ACE SWICS/SWIMS data provides charge state distributions for Carbon, Oxygen, Neon, Magnesium, Silicon, and Iron in the solar wind, as opposed to averaged values. The dataset, produced by NASA, represents a major update with redesigned analysis methods to account for instrumental and statistical effects, offering improved time series measurements for elemental abundance, charge state composition, and kinetic properties. It includes statistical error estimates and data quality flags, with the last metadata update recorded in March 2026.
ACE SWICS Version 1.1 data provides hourly measurements of solar wind ion composition, speeds, and charge states from before August 23, 2011. The dataset includes parameters like Fe/O abundance ratio, average charge states for C, O, Mg, Si, Fe, and a solar wind type classifier for streamer, coronal hole, or CME events. NASA produced this release with redesigned analysis methods to improve time series measurements and provide statistical error estimates.
NASA's Advanced Composition Explorer (ACE) satellite provides daily measurements of solar wind plasma properties. The Solar Wind Ion Composition Spectrometer (SWICS) data includes elemental and isotopic abundance ratios, average charge states, ion speeds, thermal speeds, and a solar wind type classifier. This Level 2 dataset represents an updated release with improved time series measurements and statistical error estimates.
ACE SWICS data uniquely determines the chemical and ionic charge state composition of the solar wind, measuring speeds above 300 km/s for protons. This Level 2 release from NASA uses redesigned analysis methods to account for instrumental effects and provide statistical error estimates. The dataset includes a solar wind type parameter classifying wind as streamer, coronal hole, CME, or unidentified.
The Ocean Biology DAAC produces near real-time (NRT) Fluorescence Line Height (FLH) data using satellite measurements from the Terra MODIS instrument. This data suite quantifies red chlorophyll-a fluorescence emitted by phytoplankton, measured in units of W m⁻² µm⁻¹ sr⁻¹. It is designed for rapid monitoring, though inputs and calibration are noted as less than optimal.
