GIS and Remote Sensing Unit at FEM-CRI - pyModis pyModis is a Free and Open Source Python based library to work with MODIS data. It offers bulk-download for user selected time ranges, mosaicking of MODIS tiles, and the reprojection from Sinusoidal to other projections, convert HDF format to other formats. pyModis library was developed to replace old bash scripts developed by Markus Neteler to download MODIS data from NASA FTP server. It has several features: it is very useful for downloading large numbers of MODIS HDF/XML files and for using this in a cron job for automated continuous updating; it support FTP and HTTP NASA repositoryit can parse the XML file to obtain information about the HDF filesit can convert a HDF MODIS file to GEOTIF file using MODIS Reprojection Toolit can create a mosaic of several tiles using MODIS Reprojection Tool and can create the xml metadata file with the information of all tiles used in mosaic Contents:
SeaSTA for NASA World Wind for World Wind is a comprehensive collection of high resolution maps of Sea Surface Temperature (SST) from 1982 to the latest available data. Data categories include monthly SST, SST Anomaly (SSTA) and worldwide tropical storms, hurricanes, cyclones and typhoons. also includes climatologies, an assortment of SST properties, sea ice, surface currents and winds, as well as shaded relief maps and vector outlines. This World Wind add-on contains over 800 maps covering numerous aspects of global SST. It also includes tracks and properties of over 2800 tropical storms. allows you to readily visualize the complex thermal processes that underlie the behavior of Earth's largest climatic and biological engine. contains high resolution (~4 km) monthly maps of SST from 1982 to the present. also provides monthly maps of SST Anomaly with or without contours. incorporates maps of Surface Currents, Surface Winds and Sea Ice.

NASA Earth Observatory : Home Globsnow The GlobSnow project aims at creating temporally and spatially extensive snow products with well known accuracy characteristics. The snow products will be based on current state of the art algorithms that can be employed for global scale snow monitoring. Two snow parameters: snow extent (SE) and snow water equivalent (SWE) are produced within GlobSnow. The snow products will be validated using an extensive ground truth database gathered from Canada, Scandinavia, Russia and the Alps. The currently released prototype data sets have been made publicly accessible through a FMI hosted FTP-server; access information to the server can be acquired through Dr. Global areal snow extent -product (SE) The areal snow extent product will be based on satellite-based optical data. Snow water equivalent -product (SWE) The snow water equivalent product will be based on the combination of satellite-based microwave radiometer and ground-based weather station data.

If a coral is severely bleached, disease and partial mortality become likely, and the entire colony may die. Continuous monitoring of sea surface temperature at global scales provides researchers and stakeholders with tools to understand and better manage the complex interactions leading to coral bleaching. The Coral Reef Watch mission is to utilize remote sensing and in situ tools for near-real-time and long term monitoring, modeling and reporting of physical environmental conditions of coral reef ecosystems. Coral Reef Watch is part of the NOAA Coral Reef Conservation Program (CRCP) and the National Environmental Satellite Data and Information Service (NESDIS).
