PERFORMANCE WORK STATEMENT

Aircraft Research Flights, Africa

1305M322QNRMJ0066

PURPOSE:

The National Oceanic Atmospheric Administration (NOAA) Global Monitoring Laboratory (GML) requires aircraft flights for atmospheric measurements over Africa. GML operates a global network of sites for collecting measurements of atmospheric trace gases, including greenhouse gases and ozone-depleting substances, to track their distributions and trends. A gap in GML’s atmospheric observing capability exists for Africa, which negatively impacts GML’s ability to accurately describe global emission trends, distributions, and climate system feedbacks.

Aircraft flights over Africa making measurements of atmospheric trace gases will significantly enhance GML’s global coverage and observing capabilities and are needed to improve our understanding of global emissions for air quality and climate science studies in support of the NOAA mission.

BACKGROUND:

GML also takes trace gas measurements on research aircraft conducting flights during short-term projects to quantify sources and sinks from ecosystems, industrial point sources, urban areas, and to characterize trace gas distributions in remote regions. The use of contract aircraft in Africa will allow NOAA GML to collect four-dimensional data on a routine and ongoing basis where there is currently a large geographical gap in atmospheric trace gas data coverage. Such expanded data coverage over Africa is required to improve estimates of global distributions of trace gases, quantify emissions from a rapidly changing region of the world, provide inputs for air quality and climate models, and evaluate satellite retrievals made over the continent.

SCOPE OR MISSION:

GML requires contract aircraft service providers to take atmospheric measurements of trace gases (CO2, CH4, and CO) and related parameters according to GML specifications and procedures on routine flights at altitudes of 500-25,000 feet or higher at locations over Africa.

WORK TO BE PERFORMED:

The contractor will take trace gas measurements on directed research flights and/or ride-along flights, as requested by GML. Flight plans for research flights will be developed in consultation with GML, will generally include vertical profile maneuvers spanning altitudes of 500 ft above ground level and up to 25,000 ft above sea level, and may be adjusted based on weather and safety considerations. For ride-along flights, the contractor will identify candidate flights that are scheduled for non-research purposes (e.g., transportation of passengers or cargo), on which measurement data may be acquired. The contractor will be responsible for modifying the aircraft to supply an uncontaminated air sample for measurement, to obtain reliable meteorological and Global Positioning System (GPS) data, and to power and carry the measurement equipment. The contractor will be responsible for obtaining the permits necessary for aircraft modifications and to perform research flights. The contractor will provide personnel to install and operate the measurement equipment on the aircraft according to Government provided protocols and specifications. The contractor will perform all work at their facility.

LOCATION OF WORK:

Contractor must have one or more aircraft that can be fly to an altitude of at least 15,000 ft, but preferably up to 25,000 ft while instrumented according to the specifications given below. Data collection flights may occur anywhere over and/or offshore (i.e. within 1,000 km) of Africa and more specific geographical regions within Africa may be specified within individual task orders.

Data may be collected on dedicated research flights along routes chosen by GML in consultation with the contractor to provide data for specific research goals and/or on ride-along flights occurring on predetermined routes primarily for non-GML purposes. Instrumented aircraft must be available to perform data collection flights at a minimum of once every two months for at least one year.

TECHNICAL SPECIFICATIONS:

Candidate contractors must instrument aircraft according to the following technical specifications for measuring atmospheric trace gases and collecting related meteorological and GPS data. Instrumentation listed in Table 1 may be expanded or modified in individual task orders to allow for measurement of different parameters.

1. Installation of the measurement system listed in Table 1 on the aircraft according to NOAA-provided instructions.

2. Demonstration of successful measurement collection via a ground test and flight test in coordination with GML personnel.

3. A sampling inlet of no more than 30 feet in length that results in uncontaminated sampling of the ambient outside air with no influence from cabin air or aircraft engine exhaust (at the 10, 1 and 4 parts per trillion level for CO2, CH4, CO respectively).

4. A warmup period of at least 60-minutes prior to take off with uninterrupted power to the measurement system. Table 1 lists a power backup system that will be included with the measurement system and will allow 20 minutes without aircraft power to avoid short interruptions in power to the measurement system.

5. Access to a GPS antenna that is mounted on the aircraft exterior for connecting to the

GPS receiver in the measurement system.

6. Access to an exterior mount location next to air sampling intake for the temperature/humidity probe listed in Table 1.

7. Measurements from each dedicated flight must reach altitudes of 25,000 feet above sea level or greater.

8. Climb and descent rates approximately 500 feet per minute and not exceeding 1000 feet per minute during vertical profile maneuvers on dedicated flights.

9. Transmission of raw data from the instrument package to NOAA within 24 hours of the end of each flight via cell modem to the cloud, or else by downloading files to an external storage device and sending via email.

10. Return of Government Furnished Equipment (the measurement system and all its components, as listed in Table 1) to NOAA in the same condition that they were received. If GFE is lost, stolen, or damaged beyond repair, the cost of replacement will be covered by the vendor.
