Evolution in Cloud Population Statistics of the MJO: From AMIE Field Observations to Global-Cloud Permitting Models Final Report

This is a multi-institutional, collaborative project using a three-tier modeling approach to bridge field observations and global cloud-permitting models, with emphases on cloud population structural evolution through various large-scale environments. Our contribution was in data analysis for the generation of high value cloud and precipitation products and derive cloud statistics for model validation. There are two areas in data analysis that we contributed: the development of a synergistic cloud and precipitation cloud classification that identify different cloud (e.g. shallow cumulus, cirrus) and precipitation types (shallow, deep, convective, stratiform) using profiling ARM observations and the development of a quantitative precipitation rate retrieval algorithm using profiling ARM observations. Similar efforts have been developed in the past for precipitation (weather radars), but not for the millimeter-wavelength (cloud) radar deployed at the ARM sites.

Discharge Permit-1845 Quarterly Status Report October 2018

Trichloroethene (TCE) and nitrate have been identified as constituents of concern in groundwater at the Sandia National Laboratories, New Mexico (SNL/NM) Technical Area (TA)-V Groundwater (TAVG) Area of Concern (AOC) based on detections above the U.S. Environmental Protection Agency (EPA) maximum contaminant level (MCL) in samples collected from monitoring wells. The EPA MCLs and the State of New Mexico drinking water standards for TCE and nitrate are 5 micrograms per liter and 10 milligrams per liter (as nitrogen), respectively. A phased Treatability Study/Interim Measure (TS/IM) of in-situ bioremediation (ISB) is being implemented to evaluate the effectiveness of ISB as a potential technology to treat the groundwater contamination at the TAVG AOC (New Mexico Environment Department [NMED] April 2016). The NMED Hazardous Waste Bureau (HWB) approved the Revised Treatability Study Work Plan (TSWP) (SNL/NM March 2016) in May 2016 (NMED May 2016). The SNL/NM Environmental Restoration Operations personnel are responsible for implementing the TS/IM of ISB at TAVG AOC in accordance with the Revised TSWP. Per the Revised TSWP, up to three injection wells (TAV-INJ1, TAV-INJ2, and TAV-INJ3) would be installed at TA-V in the vicinity of the highest contaminant concentrations detected in groundwater at monitoring wells LWDS-MW1, TAV-MW6, and TAV-MW10. The injection wells would be used to gravity-inject substrate solution and biodegradation bacteria to groundwater. The substrate solution consists of an inert tracer as well as essential food and nutrients for biostimulation. The substrate solution would be prepared in aboveground tanks. The TS/IM would be conducted in two phases: Phase I includes a pilot test followed by full-scale injection at the first injection well (TAV-INJ1); Phase II includes full-scale injections at the second and third injection wells (TAV-INJ2 and TAV-INJ3). The NMED Ground Water Quality Bureau (GWQB) requires a groundwater Discharge Permit (DP) for the operation of injection wells. NMED GWQB issued the DP-1845 to the U.S. Department of Energy/National Nuclear Security Administration (DOE/NNSA) for the SNL/NM TA-V Treatability Study injection wells on May 26, 2017 (NMED May 2017). The DP-1845 term started on May 30, 2017 and ends on May 30, 2022. Attachment A provides a copy of DP-1845. This quarterly report provides responses to DP-1845 Operating Conditions Terms and Conditions #3 through #8 and Monitoring and Reporting Terms and Conditions #10 through #17 for the April 1 to June 30, 2018 reporting period. The other Terms and Conditions are NMED statements of fact and do not require a response.

An eddy-permitting ocean-sea ice general circulation model (E3SMv0-HiLAT03): Description and evaluation

We document modeling setups and present results for simulated ocean and sea ice climate from a recently developed, intermediate-resolution global ocean-sea ice model [Energy Exascale Earth System Model version 0 configured for High-Latitude Application and Testing at 0.3° resolution (E3SMv0-HiLAT03)]. The horizontal resolution of HiLAT03 ranges from 33 km in the tropics to 8.5 km at high latitudes, with 100 vertical levels. This resolution allows the explicit representation of some mesoscale eddies, particularly at lower latitudes, therefore being named as an “eddy-permitting model”. Analyses are presented based on the output of two 186-yr control simulations forced by modern atmospheric conditions of climatological and inter-annually varying data sets, respectively. Results are compared to available observational data sets and the 1° NCAR model, which has somewhat similar ocean physics but a coarser resolution and an earlier version of the sea ice component. Analyses focus on ocean temperature and salinity fields, ocean dynamics and circulations, sea ice concentrations and thicknesses. The HiLAT03 model does reasonably well in most oceanic aspects evaluated here, especially in ocean meridional heat transport, despite the fact that no explicit eddy parameterization is applied. Many Arctic sea ice features are much improved compared with the 1° NCAR model, but the Antarctic summer sea ice is still generally low in concentrations and thicknesses. In addition, we discuss the prolonged deep convection (“Antarctic prolonged polynya”) over the Southern Ocean in the inter-annually forced case.

Understanding streamlined solar permitting practices: A primer

A significant “soft cost” barrier to the growth of the residential solar PV market is the length of time and cross-jurisdictional inconsistency associated with the process by which PV system installations are built according to code, permitted by the local building department, and interconnected to the grid (see Burkhardt et al. 2015 for cost estimates).
