Radio Supernovae in the Great Survey Era
, 2011 Radio properties of supernova outbursts remain poorly understood despite longstanding campaigns following events discovered at other wavelengths. After ~ 30 years of observations, only ~ 50 supernovae have been detected at radio wavelengths, none of ...

Mapping the Spatial Scales of Australian Extreme Precipitation Using Daily Rain Gauges
International Journal of Climatology, EarlyView.We present the first continent‐wide analysis of the spatial scales of daily extreme precipitation events (EPEs) in Australia using station observations and semivariogram analysis. EPEs generally have larger spatial scales at higher latitudes, with strong seasonal and regional differences shaped by topography, meteorological regimes, and climate ...

Attitude-referenced radiometer study. Part 2: Primary calibration system [PDF]
A primary calibration system, PCS, for infrared radiometers has been developed, built, and tested. The system allows radiometers to be calibrated with less than 1 percent error for use in earth coverage horizon measurements, earth resources surveys, and ...

Heat and Cold Waves in Brazil: An ERA5‐Based Analysis of Trends and Seasonality (1980–2024)
International Journal of Climatology, EarlyView.This study uses ERA5 reanalysis data to assess changes in extreme heat and cold events across Brazil from 1980 to 2024. Results reveal a sharp increase in heatwave frequency and a general decline in coldwave occurrences, though regional variations are substantial.

Case studies of NOAA 6/TIROS N data impact on numerical weather forecasts [PDF]
, 1984 The impact of satellite temperatures from systems which predate the launching of the third generation of vertical sounding instruments aboard TIROS N (13 Oct 1978) and NOAA 6 (27 June 1979) is reported.

Seasonal Variability of Precipitating Systems in Four Radar Domains of Northeast Brazil
International Journal of Climatology, EarlyView.This study analyzes the climatology and evaluates how the physical aspects of precipitating systems are influenced by the dry and wet seasons in Northeast Brazil, highlighting seasonal variations in the frequency, size, intensity, and duration of these systems in the regions of Natal, Maceió, Petrolina, and Salvador.

Dry–Hot Compound Events Driving the 2024 Pantanal Wildfires
International Journal of Climatology, EarlyView.Extreme wildfires in the Pantanal in 2024 were driven by a cascade of heatwaves, rainfall deficits and the absence of the annual flood pulse. These conditions dried soils and rivers, enhanced fuel accumulation and enabled early and intense fire outbreaks.
