Abstract Maize production in low-yielding regions is influenced by climate variability, poor soil fertility, suboptimal agronomic practices, and biotic influences, among other limitations. Therefore, the assessment of yields to various management practices is, others, critical for advancing site-specific measures enhancement. In this study, we conducted a multiseason calibration evaluation DSSA...

Liquid Water Inside Ceres: The icy dwarf planet Ceres (radius ≈475 km, density 2.1 g.cm−3, semi-major axis 2.8 AU) is the only body besides the Earth and Mars where carbonates have been observed along with brucite, another product of aqueous alteration [1]. Ceres will be visited by the Dawn spacecraft in 2015, which will offer an opportunity to constrain the origin of this large icy body. For e...

We use the clathrate hydrate trapping theory (Lunine & Stevenson 1985) and the gas drag formalism of Weidenschilling (1977) to calculate the composition of ices incorporated in the interior of Ceres. In the spirit of the work of Cyr et al. (1998), and using a time dependent solar nebula model, we show that icy solids can drift from beyond 5 AU to the present location of the asteroid and be pres...

[1] Clouds and the Earth’s radiant energy system (CERES) is a satellite-based remote sensing system designed to monitor the Earth’s radiation budget. In this paper we examine uncertainties in the angular distribution models (ADMs) used by CERES over permanently snow covered surfaces with clear skies. These ADMs are a key part of the CERES data processing algorithms, used to convert the observed...

The increase in irrigated maize plantings Northern China has increased the demand for irrigation water region, resulting chronic shortages drier years. Efficient and use are essential sustainable development management of resources area. This research applied DSSAT-maize Loess Plateau (Fenhe basin) to determine suitable optimum sowing dates ensure stability spring production. model was calibrat...

This paper presents an overview of the CERES project. It demonstrates how algorithm improvements have lead to improved top-of-atmosphere (TOA) radiative flux accuracy. CERES shortwave flux anomalies are compared with those from Earthshine and ISCCP-FD. OCIS codes: (010.1310) Atmospheric scattering

[1] Using broadband shortwave radiance measurements from the Clouds and Earth Radiant Energy System (CERES) sensors onboard the Terra and Aqua satellites, empirical angular distribution models (EADM) are constructed for smoke aerosols. These EADMs are constructed for smoke aerosols emitted during the biomass burning season (August‐October), in South America. All available years (2000–2008) of b...

Ceres is the most massive body of the asteroid belt and contains about 25 wt.% (weight percent) of water. Understanding its thermal evolution and assessing its current state are major goals of the Dawn Mission. Constraints on its internal structure can be inferred from various observations. Especially, detailed knowledge of the rotational motion can help constrain the mass distribution inside t...
