The LBA-ECO program is one of several international research components under the Brazilian-led Large Scale Biosphere?Atmosphere Experiment in Amazonia (LBA). The field-oriented research activities of this study are organized along transects and include a set of primary field sites, where the major objective is to study land-use change and ecosystem dynamics, and a smaller set of 15 operational eddy flux tower sites, where the major objective is to quantify net exchange of CO2 with the atmosphere. To supplement these studies and help to address issues of fine-scale spatial heterogeneity and scaling, high-resolution satellite imagery (IKONOS, 1?4 m) have been acquired over some of these study sites. This paper begins with a description of the acquisition strategy and IKONOS holdings for LBA. This section is followed with a review of some of the most promising new applications of these data in LBA. |

A study was carried out to verify the application of a simple approach for water potential evaluation on mango (Mangifera indica, L). Data were collected on mango ?Tommy Atkins?, cropped under drip irrigation condition, at Embrapa Semi-Árido, Petrolina-PE., Brazil. Data were obtained with a pressure chamber and correlated with psychrometric chamber measurements. Chamber pressure was halted at each 0.1 MPa for sap sampling with filter paper for differentiation between he esin and water outflow. Resin exudation was distinguished by the appearance of dark dots on the paper. The results showed that there was no correlation between the methods at 1% probability level when the values obtained at the moment of resin exudation were used. However, data obtained at the moment of water outflow were significantly correlated through the equation Y= 0.1678 + 1.151 (X) and R= 0.98 **. The results suggest that the use of filter paper to detect the moment of water outflow may help obtaining accurate pressure chamber water potential measurement on mangoes. |
