Assessment of atmospheric emissivity models for clear-sky conditions with reanalysis data
Morales-Salinas, Luis; Ortega-Farias, Samuel; Riveros-Burgos, Camilo; Chávez, José L.; Wang, Sufen; Tian, Fei; Carrasco-Benavides, Marcos ; Neira-Román, José; López-Olivari, Rafael; Fuentes‑Jaque, Guillermo (2023)Atmospheric longwave downward radiation (Ld) is one of the significant components of net radiation (Rn), and it drives several essential ecosystem processes. Ld can be estimated with simple empirical methods using atmospheric ...

Calibration and validation of an aerodynamic method to estimate the spatial variability of sensible and latent heat fluxes over a drip-irrigated Merlot vineyard
Carrasco-Benavides, Marcos ; Ortega-Farías, Samuel; Morales-Salinas, Luis; Poblete-Echeverría, Carlos ; Chavéz, José L. (2017)A study was carried out to calibrate and validate the aerodynamic temperature method for estimating the spatial variability of the sensible (H) and latent (LE) heat fluxes over a drip-irrigated merlot vineyard located in ...

Effect of missing data on short time series and their application in the characterization of surface temperature by detrended fluctuation analysis
López-Díaz, Juan L.; Hernández, Sergio; Urrutia-Sepúlveda, Angélica; López-Cortés, Xaviera A.; Araya, H.; Morales-Salinas, Luis (2021)Climate change is deeply impacting the society on different scales. Decision making becomes a complex task when, in adverse weather conditions, the meteorological records show missing data due to failures of measuring ...

Monthly calibration of Hargreaves–Samani equation using remote sensing and topoclimatology in central-southern Chile
Carrasco-Benavides, Marcos ; Morales-Salinas, Luis; Ortega-Farías, Samuel; Riveros-Burgos, Camilo; Neira-Román, José; López-Olivari, Rafael (2017)Reference evapotranspiration (ETo) has a key role in irrigation scheduling. In this sense, the Hargreaves–Samani equation (HS) is a reliable and widely used method to estimate ETo. The HS equation just requires temperature ...

Parameterization of the satellite-based model (METRIC) for the estimation of instantaneous surface energy balance components over a drip-irrigated vineyard
Carrasco-Benavides, Marcos ; Ortega-Farías, Samuel; Lagos, Luis Octavio; Kleissl, Jan; Morales-Salinas, Luis; Kilic, Ayse (2014)A study was carried out to parameterize the METRIC (Mapping EvapoTranspiration at high Resolution with Internalized Calibration) model for estimating instantaneous values of albedo (shortwave albedo) (αi), net radiation ...

Validation of gas diffusivity models with chilean soil samples
Neira-Román, José; Ortíz, Mauricio; Rolston, Dennis; Morales-Salinas, Luis; Seguel Seguel, Oscar; Riveros-Burgos, Camilo; Acevedo, Edmundo (2021)This study compares the goodness of fit of 10 empirical models used to predict gas diffusivity (Dp D0−1) with experimental data obtained from Chilean soil samples from different soil management practices. Nine sites under ...
