Huge amounts of climate and remote sensing data have been stored by several institutions in the past few years. Properly analyzed, these databases can reveal useful information, which can help researchers to monitor and esti­ mate the production of agricultural crops. Recently, the information and knowl­ edge discovered from these data have also been used for research on climate changes as well...

in recent years, mangrove forests with the high economical and environmental value are threatened with extinction by human activities. ex-situ conservation is an appropriate method to conservation this forest. this study was conducted with the purpose of studying the role of climatology factors as one of the most important environmental parameters in dispersion of mangrove forests of hormozgan ...

The International Satellite Cloud Climatology Project (ISCCP) has been approved as the first project of the World Climate Research Programme (WCRP) and will begin its operational phase in July 1983. Its basic objective is to collect and analyze satellite radiance data to infer the global distribution of cloud radiative properties in order to improve the modeling of cloud effects on climate. ISC...

[1] Global land evapotranspiration (E) between 1982 and 2011 was estimated by using a canopy conductance-based process E model (Air Relative Humidity-Based Two-Source model) [Yan et al., 2012]. To analyze the impact of precipitation forcing on E, an ensemble of six E data sets was derived from a driving ensemble of six precipitation data sets (i.e., Global Historical Climatology Network, Global...

[1] Planetary boundary layer (PBL) processes control energy, water, and pollutant exchanges between the surface and free atmosphere. However, there is no observation‐ based global PBL climatology for evaluation of climate, weather, and air quality models or for characterizing PBL variability on large space and time scales. As groundwork for such a climatology, we compute PBL height by seven met...

Monthly circulation of the South Atlantic Bight is diagnosed using a 3-D, shallow water, finite element model forced with monthly wind stress and hydrographic climatology. Temperature and salinity observations from the period 1950-99 are objectively interpolated onto the model domain, and Comprehensive Ocean-Atmosphere Data Set (COADS) wind velocities from 1975-1999 are used to prescribe the mo...

Rayleigh and Raman scatter measurements from The University of Western Ontario Purple Crow Lidar (PCL) have been used to develop temperature climatologies for the stratosphere, mesosphere, and thermosphere using data from 1994 to 2013 (Rayleigh system) and from 1999 to 2013 (vibrational Raman system). Temperature retrievals from Rayleigh-scattering lidar measurements have been performed using t...

African societies are dependent on rainfall for agricultural and other water-dependent activities, yet rainfall is extremely variable in both space and time and reoccurring water shocks, such as drought, can have considerable social and economic impacts. To help improve our knowledge of the rainfall climate, we have constructed a 30 year (1983–2012), temporally consistent rainfall data set for ...

1) Why did the authors consider a zonal mean climatology for their baseline? Why not use a spatial (lat-lon) climatology? Over the SH the stratosphere and the ozone layer have a distinct asymmetry determined by the presence of the quasi stationary wave 1. Furthermore, as noted in Malanca et al. (2005), this important aspect of mid to high latitude TOC has changed over time both in intensity and...
