Voyager 2 Hourly Magnetic Field Data from 1990-2004

This data set contains hour averages of the interplanetary magnetic field (IMF) measurements obtained by the triaxial fluxgate magnetometer (MAG) experiment on Voyager 2. Identical instruments on Voyager 1 and 2 were designed to measure the IMF between Earth and Saturn (10 AU) during the primary Voyager mission. The design and performance yielded absolute accuracies to better than 0.1 nT. In general, each component of the IMF hourly average has an uncertainty of up to (+/- 0.05 nT) in the region beyond 10 AU. More accurate measurements can be obtained by special processing of the data, but it was not feasible to do this for the entire data set included here. The magnetic field magnitude in nT is provided along with angles of the field vector in the spacecraft-centered Heliographic (HG) coordinate system, also known as RTN. The X-HG axis is directed from the Sun to the spacecraft, Y-HG is the cross product of the solar rotation axis and X-HG, and Z-HG completes the orthogonal axis system. The accompanying format description file defines the transformation of the HG angles to vector components. Cartesian coordinates are given for the spacecraft in the sun-centered Inertial Heliographic (IHG) system, where the Z-IHG axis is parallel to the solar rotation axis, X-IHG points towards the ascending node direction of the solar equator's intersection with the Ecliptic, and Y-IHG is parallel to the solar equator and completes the orthogonal system. The MAG instruments are described by K. W. Behannon et al., Space Science Reviews, 21, 235, 1977. The data and coordinates are described by L. F. Burlaga, Space Science Reviews, 39, 255, 1984. These data are from 1990-2004 and do not include spacecraft position data whereas the 1977-1989 data do. The seperation into two data products resulted from the fact that mean fields were falling towards the instrumentation digitization resolution. The Voyager/MAG team temporarily stopped production while they addressed the issue. Subsequent production in 1990 resulted in a similar data set, but without the spacecraft position. This data set is also related to the 1-hour merged Voyager mag and plasma data set. These associations are listed below using the SPASE AssociationID notation.

AIM/CIPS polar mesospheric cloud and gravity wave images and numerical data

The AIM Cloud Imaging and Particle Size instrument (CIPS) is a panoramic imager that measures solar ultraviolet radiation scattered by the atmosphere back to the satellite. The fundamental measurement is an albedo, which is the measured radiance divided by the input solar irradiance.  From the measured albedo, the presence and structure of PMCs and gravity waves (GWs) are derived.  CIPS PMC data products include cloud albedo, particle radius, and ice water content.  GWs can be inferred from the Rayleigh Albedo Anomaly (RAA) data product, which shows GW-induced albedo deviations from the background atmosphere.  PMC and RAA images are available since May of 2007.  Data products have \n56.25 km2 spatial resolution and are available on a per-orbit basis; PMC data are also available as daily maps and as season-long summary files.\n

ACE Solar Wind Electron Proton Alpha Monitor (SWEPAM) Suprathermal Electron Pitch Angle 128-Second Level 3 Data

Suprathermal Electron Pitch Angle data from ACE/SWEPAM. Level 3 data, 128-second averages. These pitch angle distributions are calculated automatically by a computer code, and have not been validated by a person. It is therefore likely that they include some artifacts and erroneous values. These data files contain suprathermal electron pitch angle distribution functions (s^3 cm^-6) at 272 eV from the ACE/SWEPAM-E instrument. The energy channel is ~12% wide, centered at 272 eV. Pitch angle bins are 9 degrees wide, and run from 0 to 180 degrees (so 0-9, 9-18, 18-27 degrees, etc.). The break between the core and suprathermal electrons is generally around 70 eV at 1 AU, but varies around this value, at times exceeding 100 eV. Electrons at 272 eV are generally well within the suprathermal range, and the distribution at this energy typically shows very little contribution from the core population. The measured count rates at 272 eV energy provide excellent statistical significance. In addition, because of the high count rates, very few artifacts (for example due to sunlight contamination) are seen in the data at this energy. The data are in the solar wind frame, and have been corrected for the spacecraft potential. The spacecraft potential determination requires measurement of the lower energy electrons, and so the potentials calcuated at these times have been interpolated to the times of the suprathermal electron measurements. Transformation to the solar wind frame requires interpolation of the measurements (each at a different energy in the solar wind frame) to the desired energy (272 eV). Also note that the detector gains on the SWEPAM-E instrument change over time, including both slowly decreasing gains and abrupt increases when the instrument voltages are increased. The use of these data for long-term studies of the distribution function amplitudes is therefore strongly discouraged.

ASTER Digital Elevation Model V004

The Terra Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Digital Elevation Model (AST14DEM) product is generated using bands 3N (nadir-viewing) and 3B (backward-viewing) of an ASTER [Level 1A](https://doi.org/10.5067/ASTER/AST_L1A.004) image acquired by the Visible and Near Infrared (VNIR) sensor. The VNIR subsystem includes two independent telescope assemblies that facilitate the generation of stereoscopic data. The band 3 stereo pair is acquired in the spectral range of 0.78 and 0.86 microns with a base-to-height ratio of 0.6 and an intersection angle of 27.7 degrees. There is a time lag of approximately one minute between the acquisition of the nadir and backward images. For a better understanding, refer to the [diagram](https://lpdaac.usgs.gov/documents/301/ASTER_Along_Track_Imaging_Geometry.png) depicting the along-track imaging geometry diagram of the ASTER VNIR nadir and backward-viewing sensors.

Arabian Sea bio-optical and biogeochemical data for ocean color validation

This project will collect high-quality, bio-optical, and biogeochemical data for validation of advanced satellite products from PACE OCI for the Arabian Sea, a highly under-sampled region of the worlds oceans, now experiencing dramatic ecosystem changes from human activities and climate-change. Over the past two decades, the base of the food chain of this monsoonal-driven ecosystem has transitioned from diatoms to one dominated by the mixotrophic dinoflagellate, Noctiluca scintillans (Noctiluca) that forms intense and widespread blooms visible from space. Capturing such phytoplankton transitions has been the pursuit of ocean color missions for more than three decades, and with its hyperspectral capabilities, NASAs PACE mission can now provide unprecedented insight into the response of phytoplankton communities to global pressures. Despite the dramatic rates at which the Arabian Sea has been changing, it remains among the most optically under-sampled of global water bodies. As part of this effort, we will leverage our long-standing ties with colleagues in India to collect high quality, high resolution (sub-pixel scale), continuous, underway and discrete bio-optical measurements to validate standard and advanced ocean products from PACE, essential to advance our understanding of vulnerable marine ecosystems and their response to anthropogenic change. As part of this activity, we plan to participate in one pre-monsoon cruise (2025) led by Space Applications Centre, ISRO, India, and two post-bloom ONR led cruises in April-May of 2024 and in April-May 2025. The pre-monsoon cruises are being undertaken as part of an Indo-US study focused on establishing triggers of the southwest monsoon rainfall season over the Indian sub-continent. Some of the data shared under this DOI is part of the Arabian Sea Marine environment through Science and Advanced Training (EKAMSAT) collaborative effort between the Ministry of Earth Sciences, Govt. of India and the Office of Naval Research. EKAMSAT commenced with a pilot study in June 2023. The pilot data is being archived under the SeaBASS experiment EKAMSAT_Pilot_ASTRAL (DOI: 10.5067/SeaBASS/EKAMSAT_Pilot_ASTRAL/DATA001) and can downloaded here: https://seabass.gsfc.nasa.gov/experiment/EKAMSAT_Pilot_ASTRAL.

PHOBOS 2 MARS TERMOSCAN THERMAL/VISIBLE IMAGING EDR V1.0

In February and March, 1989, the Termoskan instrument on board the Phobos '88 spacecraft of the USSR acquired a limited set of very high resolution simultaneous observations of the reflected solar flux (hereafter referred to as the visible channel) and emitted thermal flux (thermal infrared (IR)) from Mars's equatorial region. These are, so far, the highest spatial resolution thermal data ever obtained for Mars. Four slightly overlapping thermal panoramas (also called scans or swaths) cover a large portion of the equatorial region from 30 deg.S to 6 deg.N latitude. Simultaneous visible panoramas were taken during each of the four observing sessions; due to spacecraft memory limitations, visible channel processing was stopped early relative to the thermal channel for 2 of the sessions (2 and 4). Thus, the visible channel panoramas are shorter than the thermal panoramas for these sessions. These data are saved for historical reasons; they are not considered to be of archival quality.
