Monthly SPEI dataset at 3-, 6-, and 12-month time scales in the Amazon River Basin
<p>SPEI datasets derived from the Global SPEI database webpage and developed by Vicente-Serrano et al. (2010). This product is disseminated by the Spanish National Research Council (CSIC) for the period from January 1901 to December 2018 (118 years, version 2.6). The SPEI datasets at 3-, 6-, and 12-month time scales are gridded over a 0.50-degree grid on the Amazon River Basin.

Maps of the Sustainable Development Goal (SDG) indicator 15.3.1 with its sub-indicators for the entire Amazon River Basin
<p>Maps of the SDG indicator 15.3.1 adopted by the United Nations Convention to Combat Desertification (UNCCD) together with its sub-indicators for the Amazon River Basin for the period 2001-2020. The sub-indicators are trajectory (or trend), state, and performance. The SDG indicator 15.3.1 was calculated using the procedures described in the second version of the Good Practice Guidance for SDG Indicator 15.3.1. The annual LCLU maps from the MapBiomas project at 30 m spatial resolution and the 16-day MOD13Q1 NDVI and SoilGrids dataset were used as inputs. In addition, annualized maps of drought severity derived from SPI12, SPEI12, and scPDSI are added. </p> <p>A total of seven GeoTIFF files in Geographic Tagged Image File Format (GeoTIFF) format are provided at 250 m spatial resolution.</p> <p>Coding for the SDG indicator 15.3.1, trajectory, state, and performance.</p> <p>-32768 is ‘No data’</p> <p>-1 is ‘Degraded’</p> <p>0 is ‘Stable’’</p> <p>1 is ‘Improvement’</p> <p>Coding for the drought severity.</p> <p>From 0 (minimum drought severity) to 1 (maximum drought severity).</p>
Annotation of metagenome-assembled genomes retrieved from Amazon river basin metagenomes
<p> </p> <p><strong>Annotation of metagenome-assembled genomes retrieved from Amazon river basin metagenomes</strong></p> <p> </p> <p> RELEASE MAG-2018/01<br> --------------------------------------</p> <p> </p> <p>1. INTRODUCTION</p> <p>Here is deposited the genes and proteins annotation from metagenome-assembled genomes (MAGs) retrieved from Amazon river basin metaganomes (SRP044326, PRJEB25171 and SRP039390) were deposited under European Nucleotide Archive - ENA project PRJEB25176. Briefly, metagenomes were coassembled in groups by geographical location with Megahit v.1.0 and the contigs were used to a reads mapping and binning with BWA-MEM (version 0.7.12-r1039), SamTools (version 1.3.1) and Metabat (v2.12.1). MAGs with overall quality greater than 50, calculated with CheckM (version 1.0.11), were selected for refining precedures. Contigs outliers were eliminated by using RefineM (version 0.0.23). Finished MAGs were then annotated by Prokka (version 1.11) pipeline, and with the other most completes databases up to date (KEGG, UniProtKB, dbCAN, PFAM, eggNOG and COG).</p> <p> </p> <p>2.
