Comparison of Multiple Linear Regression, Cubist Regression, and Random Forest Algorithms to Estimate Daily Air Surface Temperature from Dynamic Combinations of MODIS LST Data
(Remote Sensing, 2017)Recently, several methods have been introduced and applied to estimate daily air surface temperature (Ta) using MODIS land surface temperature data (MODIS LST). Among these methods, the most common used method is statistical ... -
Comparison of Random Forest, k-Nearest Neighbor, and Support Vector Machine Classifiers for Land Cover Classification Using Sentinel-2 Imagery.
(Sensors (Basel, Switzerland), 2017)In previous classification studies, three non-parametric classifiers, Random Forest (RF), k-Nearest Neighbor (kNN), and Support Vector Machine (SVM), were reported as the foremost classifiers at producing high accuracies. ... -

Comparison of two different ocean tide models especially with respect to the GRACE satellite mission
(Scientific Technical Report / Geoforschungszentrum Potsdam; 2005, 08)The GRACE dual satellite mission (launched in March, 2002) offers the possibility of computing monthly highly accurate mean gravity fields over an expected lifetime of five years. Unfortunately, the quality of these monthly ... -
Comparison of two model calibration approaches and their influence on future projections under climate change in the Upper Indus Basin
(Climatic Change, 2020-11-10)This study performs a comparison of two model calibration/validation approaches and their influence on future hydrological projections under climate change by employing two climate scenarios (RCP2.6 and 8.5) projected by ... -
Comparison of vertical refractivity and temperature profiles from CHAMP with radiosonde measurements

Comparisons of CODE and CNES/CLS GPS satellite bias products and applications in Sentinel-3 satellite precise orbit determination
; (GPS Solutions, 2021-07-16)
To resolve undifferenced GNSS phase ambiguities, dedicated satellite products are needed, such as satellite orbits, clock offsets and biases. The International GNSS Service CNES/CLS analysis center provides satellite (HMW) ... -
Competing Effects of Droplet Sedimentation and Wind Shear on Entrainment in Stratocumulus
; (Journal of Advances in Modeling Earth Systems, 2019)
The joint effect of droplet sedimentation and wind shear on cloud top entrainment in stratocumulus is investigated with direct numerical simulations. Although it is well understood that droplet sedimentation weakens ... -
Competition between grain growth and grain-size reduction in polar ice
(Journal of Glaciology, 2011)Static (or ‘normal’) grain growth, i.e. grain boundary migration driven solely by grain boundary energy, is considered to be an important process in polar ice. Many ice-core studies report a continual increase in average ... -
Complex Basal Conditions and Their Influence on Ice Flow at the Onset of the Northeast Greenland Ice Stream
; ; ; ; ; ; (Journal of Geophysical Research: Earth Surface, 2021-03-09)
The ice stream geometry and large ice surface velocities at the onset region of the Northeast Greenland Ice Stream (NEGIS) are not yet well reproduced by ice sheet models. The quantification of basal sliding and a ... -
Complex High‐ and Low‐Flow Networks Differ in Their Spatial Correlation Characteristics, Drivers, and Changes
; (Water Resources Research, 2021-09-15)
Hydrologic extremes such as floods and droughts are often spatially related, which increases management challenges and potential impacts. However, these spatial relationships in high and low flows are often overlooked in ... -

; ; ; (Journal of Geophysical Research: Atmospheres, 2022-11-06)
Climate hazards associated with compound events (CEs) have lately received increasing attention over South America (SA) due to their potential risks and amplification of impacts. This work addressed the evaluation of ... -
Compound-Specific Radiocarbon Analysis of (Sub-)Antarctic Coastal Marine Sediments—Potential and Challenges for Chronologies
; ; ; ; ; (Paleoceanography and Paleoclimatology, 2020)
In Antarctic and Subantarctic environments, 14C-based age determination is often challenging due to unknown reservoir effects, low organic carbon contents of sediments, and high contributions of petrogenic (14C-free) carbon ... -
Comprehensive analysis of chemical and biological problems associated with browning agents used in aquatic studies
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; (Limnology and Oceanography: Methods, 2021-10-28)
Inland waters receive and process large amounts of colored organic matter from the terrestrial surroundings. These inputs dramatically affect the chemical, physical, and biological properties of water bodies, as well as ... -
