POLARIS Ground Site Data

POLARIS_Ground_Data is the ground site data collected during the Photochemistry of Ozone Loss in the Arctic Region in Summer (POLARIS) campaign. Data from the Composition and Photo-Dissociative Flux Measurement (CPFM) are featured in this collection. Data collection for this product is complete. The POLARIS mission was a joint effort of NASA and NOAA that occurred in 1997 and was designed to expand on the photochemical and transport processes that cause the summer polar decreases in the stratospheric ozone. The POLARIS campaign had the overarching goal of better understanding the change of stratospheric ozone levels from very high concentrations in the spring to very low concentrations in the autumn. The NASA ER-2 high-altitude aircraft was the primary platform deployed along with balloons, satellites, and ground-sites. The POLARIS campaign was based in Fairbanks, Alaska with some flights being conducted from California and Hawaii. Flights were conducted between the summer solstice and fall equinox at mid- to high latitudes. The data collected included meteorological variables; long-lived tracers in reference to summertime transport questions; select species with reactive nitrogen (NOy), halogen (Cly), and hydrogen (HOx) reservoirs; and aerosols. More specifically, the ER-2 utilized various techniques/instruments including Laser Absorption, Gas Chromatography, Non-dispersive IR, UV Photometry, Catalysis, and IR Absorption. These techniques/instruments were used to collect data including N2O, CH4, CH3CCl3, CO2, O3, H2O, and NOy. Ground stations were responsible for collecting SO2 and O3, while balloons recorded pressure, temperature, wind speed, and wind directions. Satellites partnered with these platforms collected meteorological data and Lidar imagery. The observations were used to constrain stratospheric computer models to evaluate ozone changes due to chemistry and transport.

Polarimetric Validation of the PACE Observatory

The Naval Research Laboratory (NRL) and the City College of New York (CCNY) operate a comprehensive suite of instrumentation to measure and characterize the uncertainty of polarized radiation, as wellÂ as particle size distributions (PSDs), particle shape characterization and imaging, advanced chlorophyll fluorescence analysis, and seawater inherent optical properties (IOPs) and constituents. Measured attenuation (c) and absorption (a) coefficients of water and the degree of linear polarization (DoLP) above the surface derived from measurements of polarized radiances at Hyper-Angular Research Polarimeter 2 (HARP2) wavelengths will be used for the validation of a newly developed neural network algorithm for the retrieval of the c/a ratio from combined Ocean Color Instrument (OCI) and HARP-2 measurements (Agagliate et al., Frontiers in Remote Sensing, 2023).

Polar Stereographic Valid Ice Masks Derived from National Ice Center Monthly Sea Ice Climatologies, Version 1

These valid ice masks provide a way to remove spurious ice caused by residual weather effects and land spillover in passive microwave data. They are derived from the National Ice Center Arctic Sea Ice Charts and Climatologies data set and show where ice could possibly exist based on where it has existed in the past. There are 12 valid ice masks, one for each month, in netCDF-CF 1.6 compliant files with all associated metadata. The data are on a 304 x 448 grid and are available via FTP.

Processing and Distribution of Hyperspectral Radiometer Data from Ships of Opportunity for Monitoring Phytoplankton in the Ocean

Ocean-colour sensors mounted on satellites can view the entire ocean over a period of a few days. However, to calibrate these sensors and validate the data, satellite observations must be compared with accurate and reliable in situ measurements, collected at the ocean surface. There are many regions of the ocean where these in situ measurements are rarely collected. Ocean-colour sensors can be mounted on research vessels and ships of opportunity. In this project, an ocean-colour sensor (Seabird HyperSAS Solar Tracker) was mounted on a yacht that visits remote regions of the planet where few observations have been collected. This project aims to process this data to a level for use by the scientific community for scientific applications, such as satellite validation.

Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) Surface Emissivity from PREFIRE Satellite 2 R01

Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) Surface Emissivity from PREFIRE Satellite 2 (PREFIRE_SAT2_2B-SFC) contains surface emissivity derived from data collected by the PREFIRE Thermal Infrared Spectrometer (TIRS-PREFIRE) aboard PREFIRE-SAT2. Dual CubeSats each carry a PREFIRE Thermal Infrared Spectrometer (TIRS-PREFIRE), a push broom spectrometer with 63 channels measuring mid- and far-infrared (FIR) radiation from approximately 5 to 53 µm. Most polar emissions are in the FIR but have not been measured on a large scale. PREFIRE aims to fill knowledge gaps in the global energy budget by more accurately characterizing polar emissions. This information will then be assimilated into global circulation and other models to predict future conditions more accurately. PREFIRE_SAT2_2B-SFC contains surface spectral emissivity for all available TIRS-PREFIRE channels as derived from PREFIRE Spectral Radiance (PREFIRE_SAT2_1B-RAD) data using an Optimal Estimation retrieval via a radiative transfer model with inputs from the PREFIRE_SAT2_AUX-MET (Auxiliary Meteorology) and PREFIRE_SAT2_2B-MSK (cloud mask) collections. The purpose of this collection is to assess surface emissivity over the polar regions to better quantify the polar radiative budget in those regions. Science data retrieval started June 29, 2024 and is ongoing. Geographic coverage is global, with the greatest concentration of data in the polar regions. Within the orbital swath there are eight distinct tracks of data associated with the eight separate spatial scenes for each PREFIRE-TIRS. At the beginning of the mission, the approximate scene footprint sizes were 11.8 km x 34.8 km (cross-track x along-track), with gaps between each scene of approximately 24.2 km. The entire swath was ~264 km across. Note that the scene footprint and swath sizes quoted here are for the orbit altitude soon after launch. However, the footprint size will slowly become smaller as the orbit altitude decreases with time. This data has a temporal resolution of 0.707 seconds and is available in netCDF-4. The surface emissivity data for the sister instrument aboard PREFIRE-SAT1 can be found in the PREFIRE_SAT1_2B-SFC collection.

Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) Surface Emissivity Sorted All-sky Climatology from PREFIRE Satellite 1 R01

Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) Surface Emissivity Sorted All-sky Climatology from PREFIRE Satellite 1 (PREFIRE_SAT1_3-SFC-SORTED=ALLSKY) contains monthly climatologies of the Level 2 PREFIRE Surface Emissivity from the PREFIRE Satellite 1 collection (PREFIRE_SAT1_2B_SFC), which is derived from data collected by the PREFIRE Thermal Infrared Spectrometer (TIRS-PREFIRE) aboard PREFIRE-SAT1. Dual CubeSats each carry a PREFIRE Thermal Infrared Spectrometer (TIRS-PREFIRE), a push broom spectrometer with 63 channels measuring mid- and far-infrared (FIR) radiation from approximately 5 to 53 µm. Most polar emissions are in the FIR but have not been measured on a large scale. PREFIRE aims to fill knowledge gaps in the global energy budget by more accurately characterizing polar emissions. This information will then be assimilated into global circulation and other models to predict future conditions more accurately. PREFIRE_SAT1_3-SFC-SORTED-ALLSKY climatologies include 1) gridded, time-averaged spectral emissivity sorted by surface type, and 2) gridded standard deviations of time-averaged spectral emissivity sorted by surface type. The grids are 1°x1° and time averaging is currently monthly. Spatially, the cross-track dimension is retained, which consists of 8 distinct tracks. Full swath climatologies will be generated in addition to ascending- and descending-only subsets to account for diurnal variability. The purpose of this collection is to identify surface emissivity behaviors based on surface type and to assimilate PREFIRE surface emissivity data into climate models to further understand and more accurately predict future climates. The data format is NetCDF4. The sorted surface emissivity climatologies for the sister instrument aboard PREFIRE-SAT2 can be found in the PREFIRE_SAT2_3-SFC-SORTED-ALLSKY collection
