SM2RAIN–ASCAT (2007–2018): global daily satellite rainfall data from ASCAT soil moisture observations [PDF]

Earth System Science Data, 2019
Long-term gridded precipitation products are crucial for several applications in hydrology, agriculture and climate sciences. Currently available precipitation products suffer from space and time inconsistency due to the non-uniform density of ground ...

On the characteristics of ASCAT wind direction ambiguities [PDF]

Atmospheric Measurement Techniques, 2013
The inversion of the Advanced Scatterometer (ASCAT) backscatter measurement triplets generally leads to two wind ambiguities with similar wind speed values and opposite wind directions.

Benchmarking Ploidy Estimation Methods for Bulk and Single-Cell Whole Genome Sequencing. [PDF]

Adv Sci (Weinh)
It comprehensively benchmarks computational tools for ploidy estimation from bulk and single‐cell whole‐genome sequencing data. The results highlight the strengths and limitations of each method under different conditions and identify PURPLE and SeCNV show top performance in bulk and single‐cell settings, respectively.

ASCAT IB: A radar-based vegetation optical depth retrieved from the ASCAT scatterometer satellite

Remote Sensing of Environment, 2021
Abstract Vegetation optical depth (VOD), as a microwave-based vegetation index for vegetation water and biomass content, is increasingly used to study the impact of global climate and environmental changes on vegetation. Currently, VOD is mainly retrieved from passive microwave data and few studies focused on VOD retrievals from active microwave data.

SM2RAIN-ASCAT (2007–2018): global daily satellite rainfall from ASCAT soil moisture [PDF]

, 2019
Abstract. Long-term gridded precipitation products are crucial for several applications in hydrology, agriculture and climate sciences. Currently available precipitation products obtained from rain gauges, remote sensing and meteorological modelling suffer from space and time inconsistency due to non-uniform density of ground networks and the ...

Substantial non-homologous recombination and structural variation results from Brassica AABC and CCAB hybrid meiosis. [PDF]

Plant J
SUMMARY Meiotic crossovers contribute to genetic diversity and play a crucial role in homologous chromosome segregation. Non‐homologous crossovers in Brassica, involving the exchange of genetic material between genomes, can be valuable for transferring novel traits or characteristics between Brassica species.

Matching ASCAT and QuikSCAT winds [PDF]

Journal of Geophysical Research: Oceans, 2012
Surface winds from two scatterometers, the Advanced scatterometer (ASCAT), available since 2007, and QuikSCAT, which was available through November 2009, show persistent differences during their period of overlap. This study examines a set of collocated observations during a 13‐month period November 2008 through November 2009, to evaluate the causes of

Adapting the sir algorithm to ASCAT [PDF]

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
Scatterometers have been launched primarily to measure ocean winds. The value of scatterometer data is increased by application of the SIR (Scatterometer Image Reconstruction) algorithm. The SIR algorithm enhances the effective resolution of the scatterometer data to support its use for other studies.

ASCAT scatterometer ocean calibration

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
A new scatterometer, the so-called Advanced scatterometer (ASCAT), onboard MetOp-A satellite was successfully launched on October 19 2006. During the commissioning phase one of the main goals is to accurately calibrate the instrument. The radar backscatter has been calibrated using three ground-based transponders in February 2008.
