Projecting Northern Hemisphere Flow Regime Transition Using Integrated Enstrophy by Emily Klaus, Patrick Market, Anthony Lupo, Michael Bodner, Joshua Kastman

“…In this study, IE is calculated at 500 hPa over an area that encompasses 0° to 70° in the Northern Hemisphere. The data sets used were the 500 hPa initial and forecast fields for the Global Ensemble Forecasting System (GEFS) (on a 1 × 1 latitude-longitude grid) provided by the National Oceanic and Atmospheric Administration (NOAA) Weather Prediction Center (WPC) and the National Centers for Environmental Prediction/NOAA reanalyses (on a 2.5 × 2.5 latitude-longitude grid) archived in Boulder, CO. …”

Faraday rotation measures of Northern hemisphere pulsars using CHIME/Pulsar by Ng, C, Pandhi, A, Naidu, A, Fonseca, E, Kaspi, VM, Masui, KW, Mckinven, R, Renard, A, Scholz, P, Stairs, IH, Tendulkar, SP, Vanderlinde, K

“…Our results represent a significant increase of the pulsar RM census, particularly regarding the Northern hemisphere. These new RMs are for sources that are located in the Galactic plane out to 10 kpc, as well as off the plane to a scale height of ∼16 kpc. …”

Faraday rotation measures of Northern hemisphere pulsars using CHIME/Pulsar by Ng, C, Pandhi, A, Naidu, A, Fonseca, E, Kaspi, VM, Masui, Kiyoshi, Mckinven, R, Renard, A, Scholz, P, Stairs, IH, Tendulkar, SP, Vanderlinde, K

“…Using commissioning data from the first year of operation of the Canadian Hydrogen Intensity Mapping Experiment’s (CHIME) Pulsar backend system, we conduct a systematic analysis of the Faraday Rotation Measure (RM) of the Northern hemisphere pulsars detected by CHIME. We present 55 new RMs as well as obtain improved RM uncertainties for 25 further pulsars. …”
