Dosimetric Intercomparison at the Scandinavian Radiation Therapy Centres I. Absorbed Dose Intercomparison [PDF]

Acta Radiologica: Oncology, 1982
A dosimetric intercomparison was carried out at all the centres in Denmark, Norway and Sweden. All the beam qualities (except conventional roentgen rays) used in radiation therapy were investigated. The ratio of the absorbed dose measured by us to that stated by the centre was determined.

Compound Hot‐Dry Days (CHDDs) and Their Implications on Maize Yields in the Free State Province, South Africa

International Journal of Climatology, EarlyView.
Compound hot‐dry events occurring during the maize growing period are increasing significantly (p < 0.05) with time, with the median values ranging from 93 to 120 days. El Niño Southern Oscillation (ENSO) influences the variability of compound hot‐dry events with high significance (p < 0.05) positive Pearson correlation.

Evaluation of CMIP6 Models in Simulating Australian Monsoon Over Northern Australia

International Journal of Climatology, EarlyView.
The study assesses CMIP6 models for their ability to simulate key aspects of the Australian summer monsoon, including precipitation patterns, wind circulation, monsoon onset/retreat, and ENSO teleconnections. Most models overestimate rainfall, underestimate wind strength, and simulate more uniform ENSO influence across northeast and northwest Australia.

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.

Assessing Past and Future Temperature‐ and Precipitation‐Based Indicators in the Republic of Yemen

International Journal of Climatology, EarlyView.
For the first time in the literature, this work assesses the past and future climatic trends over Yemen, a highly vulnerable country for which science‐based, high‐quality information for the development of climate change adaptation plans was not available until now.

Intercomparison of XH2O Data from the GOSAT TANSO-FTS (TIR and SWIR) and Ground-Based FTS Measurements: Impact of the Spatial Variability of XH2O on the Intercomparison

Remote Sensing, 2017
Spatial and temporal variability of atmospheric water vapor (H2O) is extremely high, and therefore it is difficult to accurately evaluate the measurement precision of H2O data by a simple comparison between the data derived from two different instruments.

Precipitation Products’ Inter–Comparison over East and Southern Africa 1983–2017

Remote Sensing, 2021
During recent decades East Africa (EA) and Southern Africa (SA) have experienced an intensification of hydrological hazards, such as floods and droughts, which have dramatically affected the population, making these areas two of the regions of the ...

Results from the Ice-Sheet Model Intercomparison Project–Heinrich Event Intercomparison (ISMIP HEINO) [PDF]

Journal of Glaciology, 2010
AbstractResults from the Heinrich Event Intercomparison (HEINO) topic of the Ice-Sheet Model Intercomparison Project (ISMIP) are presented. ISMIP HEINO was designed to explore internal large-scale ice-sheet instabilities in different contemporary ice-sheet models. These instabilities are of interest because they are a possible cause of Heinrich events.

User‐Relevant Climate Indices and Associated Uncertainties From Transient Convection‐Permitting Climate Model Projections

International Journal of Climatology, EarlyView.
A transient ensemble of convection‐permitting climate simulations is used to compute bias‐corrected user‐relevant climate indices for Germany under recent and future climate conditions, both considering high spatial resolution and uncertainty estimations. For high temperature indices, a clear increase is observed, for example, for hot days and tropical
