STATEMENT OF WORK (SOW)

Research and Development (R&D) of the U.S. Navy’s NEPTUNE Capability

INTRODUCTION/BACKGROUND:

The Naval Research Laboratory (NRL), Marine Meteorology Division (MMD), is part of NRL’s Ocean and Atmospheric Science and Technology Directorate, which contains six (6) divisions performing broadly based scientific research and advanced technology development in the fields of marine geosciences, acoustics, oceanography, marine meteorology, remote sensing, and space science. The MMD Division conduct basic and applied research and development (R&D) programs designed to improve scientific understanding of atmospheric processes that impact fleet operations, and develop automated systems that analyze, simulate, predict, and interpret the structure and behavior of these processes and their effect on naval weapons systems.

To accomplish its mission of conducting basic and applied research and strengthen forecasting and meteorological and atmospheric research initiatives and support the advancement of NRL MMD’s scientific community, NRL MMD requires highly specialized contractor support to the U.S. Navy’s next-generation global numerical weather prediction (NWP) system using the “Navy Environmental Prediction sysTem Utilizing a Nonhydrostatic Engine” referred to as NEPTUNE.

OBJECTIVES:

The goal of this contract effort is for the Contractor to provide unclassified support to NRL MMD’s efforts in developing and upgrading various NEPTUNE related projects listed below. The Contractor shall provide necessary personnel, unique software packages, end-to-end observation capability, the unique capability of training modules, and experience in hosting scientific workshops for the development and test of the U.S. Navy’s Next-Generation global NWP system, NEPTUNE. The following is a list of NEPTUNE long-term related projects that are critical to further the U.S. Navy’s capability of accessing the superior battlespace environment in the years to come:

· NEPTUNE dynamic core (CPAESS)

· NEPTUNE High Altitude (NEPTUNE-HA) (CPAESS)

· NEPTUNE-Tactical (limited area and regional refinement) (CPAESS)

· NIMOv2 (NEPTUNE-HA + ionospheric prediction) (CPAESS)

· ESPCv3 (implementation of NEPTUNE in ESPC system, upgrade to ESMx) (CPAESS)

· NEPTUNE-Aerosol/NAAPS (CPAESS)

· NEPTUNE physics (NSF NCAR/RAL)

· FALCON for NEPTUNE (JEDI enabled Data Assimilation) (JCSDA)

· NEPTUNE Verification and Validation (V&V) using METplus (NSF NCAR/RAL)

· NEPTUNE training modules for the sailors (COMET)

SCOPE OF WORK:

The scope of this effort is to provide comprehensive R&D in support of NEPTUNE. NRL MMD expects to receive software packages developed and tested by the Contractor to be used in future versions of the NEPTUNE systems.

Upgrade to support oneAPI version of the Intel compilers. Optimization of the input/output component of NEPTUNE. Optimize the TLM and Adjoint models.

4.1.8 In coordination with the data assimilation system efforts, the Contractor shall support the integration of NEPTUNE within the 4D-Var data assimilation system.

4.1.9 In collaboration with NEPTUNE physics and data assimilation efforts, the Contractor shall perform iterative testing of NEPTUNE initialized with 4D-Var data assimilation.

4.2 Research and development of Common Community Physics Package (CCPP) to be used in NEPTUNE through NCAR

4.2.1 The Contractor shall evaluate the real data tests of NEPTUNE for 9-km to 18-km resolution on the globe using the dual-resolution cycling system. Address systematic biases using cold starts and cycling data assimilation. Utilize already developed diagnostics and verification software for physics. Using tools from the Hierarchical Developmental System (HDS) provide evaluation and inform the tuning and calibration of the NEPTUNE physics suite. Evaluate, compare, and demonstrate the robustness of the physics and simulations for forecast lengths up to 10-day forecasts using the dual-resolution cycling system. Compare results with other modeling systems such as NAVGEM, ECMWF, and/or GFS.

4.2.2 Document the strengths and weaknesses of the system, particularly focusing on systematic biases due to the physics.

4.2.3 Advance the coupling between the boundary layer and shallow convection parameterizations, which are currently resulting in systematic errors in the tropics. Likely these systematic errors will feedback and grow in the cycling system and will need to be mitigated.

4.2.4 Implement the cap generation software in NEPTUNE for CCPP to generalize the coupling infrastructure software between NEPTUNE and CCPP.
