HQ Alice Crawford added capability to the get_era5.py, which automates the retrieval of the ERA5 grib files for conversion to ARL format. The program can now download ERA5 ensemble of data assimilations (ERA5 EDA) for use with HYSPLIT. https://github.com/amcz/hysplit_metdata. The ERA5 EDA has 62 km global resolution and 3 hourly analysis fields. There are 10…

DetailsHQ Over one million served again! In 2017, a new record was achieved for the most HYSPLIT simulation ever produced on the READY web server (http://www.ready.noaa.gov), with over one million (1,217,438) simulations performed exceeding the previous record set in 2016 (1,094,305). HYSPLIT simulations have seen a steady increase since 2009 when results were tabulated. READY…
DetailsHQ A one day HYSPLIT short course was given to 13 participants on Sunday, January 7, 2018, as part of the 98th American Meteorological Society (AMS) Annual Meeting in Austin, Texas. The short course titled, “Using PC/Mac-based HYSPLIT for Basic Trajectory and Dispersion Applications” was designed for novice HYSPLIT users and focused on the basic…
DetailsHQ Starting in early February, Xinrong Ren will participate in the Fluxes of Greenhouse Gases in Maryland (FLAGG-MD) project to continue characterizing the greenhouse gas (GHG) emissions from the Baltimore-Washington area. The University of Maryland’s Cessna 402B research aircraft will fly over this area to measure GHGs, meteorological variables, as well as other trace gases…
DetailsHQ This week the WRF/ARW meteorological model was successfully configured to be able to run through a web interface for any location selected by the user and create a HYSPLIT-compatible meteorological file. Currently, the system is designed to create 2 domains: a CONUS domain at 27 km with 6 hrs of spinup and 9 hours…
DetailsHQ Dr. Hyun Cheol Kim visited the National Institute of Environmental Research, Korea for a project progress meeting. In collaboration with Ajou University, ARL scientists (Drs. Hyun Cheol Kim, Tianfeng Chai and Fong Ngan) have worked on the Korea-Monitoring Emissions Modeling System (K-MEMs) project which aims to design a framework of State Implementation Plan in…
