There is a growing need to develop improved technologies for precise airborne measurements of carbon dioxide, CO2. CO2 measurements are of great importance to many areas of research, including climate change, global carbon budgets, and geological research in relation to volcanic activity. At the same time, we are entering a period of time in which Unmanned Aircraft Systems (UAS) are becoming more widely used for atmospheric research. UAS platforms have already proven themselves as a uniquely capable means for making measurements in remote areas and over oceans. However, existing CO2 measurement technologies are difficult to adapt to or use in the UAS world. This proposal describes a simple and inexpensive sensor for the precise determination of atmospheric CO2 that will be small enough for flight on small UAS platforms and sounding balloons. Phase I will include the fabrication of a proof-of-concept sensor system, laboratory characterization of the sensor, and culminate in a demonstration of the sensor on a UAS. Phase II will emphasize improving the basic manufacturability of the design, as well as much more extensive laboratory and UAS testing.

In Phase 1, Ridgetop Group designed a high-speed, yet low-power silicon germanium (SiGe)-based, analog-to-digital converter (ADC) to be a key element for digital beam forming (DBF) systems that will be used in NASA's future radar applications. The ADC will employ a novel combination of time interleaving, high-speed silicon-germanium BiCMOS technology and low-power techniques, such as the double-sampling technique, providing exceptional sampling speed of 500 MSPS, 1.5 GHz analog bandwidth,12 bits of resolution, and below 500 mW power dissipation, exceeding NASA's requirements. Ordinarily, ADC design requires large trade-offs in speed, resolution, and power consumption. The significance of this innovation is that it simultaneously provides a high-speed, high-resolution, and low-power ADC that is well ahead of the state of the art. These three characteristics are needed for DBF systems that contain large ADC arrays. The power consumption of existing ADC chips prohibits implementation of large DBF arrays in space. Ridgetop's innovative design leverages newer semiconductor process technologies that combine silicon and germanium into a compound semiconductor. Ridgetop has identified two Phase 2 objectives, which are: 1. Design, fabricate and characterize Test Chip 1 that contains critical ADC subcircuits. 2. Design, fabricate and characterize Test Chip 2 that contains the complete radiation tolerant, digitally calibrated, time-interleaved ADC design. During Phase 1 Ridgetop identified the topologies for all of the circuit blocks that will be included on Test Chip 1 and Test Chip 2. Ridgetop has also completed transistor-level designs for the key components on these chips. Estimated TRL at beginning and end of Phase 2 contract: Begin 4; End 8.

HAMSR is a 25-channel microwave atmospheric sounder operating as a cross-track scanner. It operates in three frequency bands centered around 53, 118 and 183 GHz. HAMSR functionality is similar to AMSU-A/B, but with additional channels. There are three bands: an 8-channel band near 50-GHz, used for primary temperature sounding; a 10-channel band near 118 GHz, used for secondary temperature sounding and assessment of scattering; and a 7-channel band near 183 GHz, used for water vapor (humidity) sounding. The instrument is continuously self-calibrating using internal calibration targets. Radiometric sensitivity at the composite sampling cells provided in the archive is typically 0.1 K and ranges up to 0.25 K for the stratospheric channels. Calibration accuracy is estimated at better than 1 K for temperature sounding and better than 2 K for water vapor sounding. Temperature weighting function peaks are distributed between the surface and the flight altitude.

The 2013 cartographic boundary shapefiles are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based shapefiles while others are available only as state-based files.

This map layer shows lines of equal annual change (secular variation) in the vertical component of the total field intensity of the Earth's magnetic field, derived from the International Geomagnetic Reference Field (IGRF) for the epoch 2010.0. Magnetic intensity is the strength of the magnetic field, and is described in terms of a horizontal component and a vertical component. The change in intensity is measured in nanoTeslas per year.

In situ, meteorological, navigational, physical and profile oceanographic data were collected, including AIR TEMPERATURE, DEPTH - OBSERVATION, HYDROSTATIC PRESSURE, LATITUDE, LONGITUDE, PRECIPITATION RATE, RELATIVE HUMIDITY, SALINITY, SEA SURFACE TEMPERATURE, SIGMA-THETA, WATER TEMPERATURE, WIND DIRECTION and WIND SPEED from Moored Buoy at the TAO/TRITON Site 8N 110W (T8N110W) using GPS, anemometer, conductivity sensor, meteorological sensors, pressure sensors and thermistor from 1999-11-12 to 2015-09-06. These data were provided to one of the OceanSITES Data Assembly Centers (DAC). The DAC formatted this information into the OceanSITES file format and passed it on to the Global Data Assembly Centers (GDAC). OceanSITES is a worldwide system of long-term, open-ocean reference stations measuring dozens of variables and monitoring the full depth of the ocean from air-sea interactions down to the seafloor. It is a network of stations or observatories measuring many aspects of the ocean's surface and water column using, where possible, automated systems with advanced sensors and telecommunications systems, yielding high time resolution, often in real-time, while building a long record.

This data set contains coarse scale elevation and elevation-based parameters at 1.0 and 0.5-degree spatial resolutions that were developed to support a wide variety of global modeling activities through the International Satellite Land Surface Climatology Project (ISLSCP) Initiative II data collection. These coarse scale data have sufficient statistical information (up to fourth moment) to allow a good statistical description of the sub-cell distribution of any particular elevation parameter (i.e. elevation, slope and aspect). The database used in the development effort was the HYDRO1k product (http://eros.usgs.gov/#/Find_Data/Products_and_Data_Available/HYDRO1K) with a native spatial resolution of 1 km, the highest resolution database of global coverage of standard elevation-based derivatives (slope, aspect, elevation, compound topographic index, etc.).

Summary

Description

Current and future programs of near-Earth and deep space exploration require the development of faster and more reliable electronics with open system architectures that are reconfigurable, fault-tolerant, and can operate effectively for long periods of time in harsh environments. Existing data transfer systems based on passive backplanes are slow, power hungry, hardly reconfigurable, and feature high latency, limited expandability, and low radiation tolerance. During Phase I, our company has proven in computer simulations the basic concept of a radiation tolerant switching fabric backplane with reconfigurable serial interfaces. During Phase II, the company proposes to develop a functional prototype of a novel, radiation-tolerant, switching fabric with user-programmable interfaces that support either Space Wire or the company's proprietary multi-level interconnect solution. The patent-pending multi-level interconnect technique provides improved serial point-to-point link functionality including lower latency, higher speed and lower power consumption. It eliminates the requirement of the second information channel utilized in Space Wire's data-strobe encoding scheme, which can be instead used as a redundant channel to improve the system's fault tolerance. The unprecedented reliability of the developed system-on-chip is guaranteed by utilization of inherently radiation-tolerant SiGe hetero-junction bipolar transistors in proprietary circuit structures that are specifically hardened to single-event effects.
