چکیده
[1] In their paper, Lanfredi et al. [2003] raise several issues about our analysis of normalized difference vegetation index (NDVI) data for areas north of 30 N between 1981 and 1999. As we describe below, their comments represent a basic misunderstanding of the data, a misrepresentation of our work, or an anticipation of our recently published results. Here we address these issues in order in which they are given by Lanfredi et al.

Reply to Comment on ‘‘Variations in northern vegetation activity inferred from satellite data of vegetation index during 1981–1999’’ by J. R. Ahlbeck
[1] Ahlbeck [2002] raises an important issue: Is the increase in the atmospheric concentration of CO2 [Keeling and Whorf, 2001] partially responsible for the increase in the normalized difference vegetation index (NDVI), which we report in the work of Zhou et al. [2001]? To demonstrate its effect, Ahlbeck [2002] adds the atmospheric concentration of CO2 (hereinafter referred to as CO2) to equat...
متن کاملDrought Effects on Vegetation Changes in Kashkan Basin of Lorestan Using ETM + and OLI Landsat Data
Background and objectives: Vegetation is one of the most important elements of an ecosystem, which is directly related to the moisture conditions of the land. Estimation of plant drought indices such as VCI, TCI, VHI is an effective tool to assess the effects of drought by calculating NDVI. In this regard, several studies have been conducted that explain how to calculate and use these indicator...
متن کاملEvaluation of land degradation trend using satellite imagery and climatic data (Case study: Fars province)
Introduction: Climate change and human activities have a direct impact on land vegetation. Decreased rainfall and increased temperature are among the climate change factors leading to significant changes in water resources and energy balance in affected areas. On the other hand, human activities such as growing population, overgrazing and land use changes that make change in land conditions, al...

Editor, I read the recent publication by Toossi et al. with a great interest (1). Toossi et al. concluded that “Average gonad and bone marrow doses for North Khorasan, Boshehr and Hormozgan provinces were less than the corresponding values for normal area (2).” There are some facts on this report to be concerned. I agree that the detected levels might be high in the mentioned area, but th...
