An intercomparison of global oceanic precipitation climatologies [PDF]

open access: yes, 2007
Large-scale patterns of precipitation are important for the changes they may effect upon the circulation of the ocean. However, marine precipitation is very hard to quantify accurately.

Precipitation response to El Niño/La Niña events in Southern South America – emphasis in regional drought occurrences [PDF]

open access: yesAdvances in Geosciences, 2016
The ENSO phenomenon is one of the key factors that influence the interannual variability of precipitation over Southern South America. The aim of this study is to identify the regional response of precipitation to El Niño/La Niña events, with emphasis

Trends in Quality Controlled Precipitation Indicators in the United States Midwest and Great Lakes Region

open access: yesFrontiers in Water, 2022
Changes in precipitation can have broad and significant societal impacts. A number of previous studies that analyzed changes in precipitation across the Great Lakes and Midwest for a variety of time periods and using a range of quality-control standards ...

Algorithms for Doppler Spectral Density Data Quality Control and Merging for the Ka-Band Solid-State Transmitter Cloud Radar

open access: yesRemote Sensing, 2019
The Chinese Ka-band solid-state transmitter cloud radar (CR) can operate in three different work modes with different pulse widths and coherent integration and non-coherent integration numbers to meet the requirement for long-term cloud measurements. The

Assessing Precipitation Delineation Capabilities of Spaceborne Radars [PDF]

open access: yes, 2022
Spaceborne radars uniquely measure, provide the finest depiction of, and give the most accurate estimate of precipitation globally from space. The Global Precipitation Measurement (GPM) mission dual-frequency precipitation radar (DPR) is the successor to

Determining the size of lightning-induced electron precipitation patches [PDF]

open access: yes, 2002
[1] We analyze Trimpi signatures during 23 and 24 April 1994 at four sites on or near the Antarctic Peninsula (Palmer, Faraday, Rothera, and Halley) on subionospheric VLF signals received from four U. S.

A case study of HF radar spectral width in the post midnight magnetic local time sector and its relationship to the polar cap boundary [PDF]

open access: yes, 2002
International audienceThe aim of this paper is to advance the current understanding of the spectral width parameter observed by coherent high frequency (HF) radars. In particular, we address the relationship of a frequently observed gradient, between low
