![]() ![]() Considering also WP in terms of fruits and coconut's water produced, it averaged 1.9 coconut fruits and 0.8 L of coconut water per cubic meter of water consumed, respectively. It was noticed some water stress conditions, with the fraction ET to reference evapotranspiration (ET 0) dropping below 0.60 from the start of August to the end of the year, affecting the WP ET values. The highest ET and BIO rates, above 4.0 ± 0.6 mm d −1 and 140 ± 37 kg ha −1 d −1, respectively, happened from May to July, retrieving WP ET pixel values larger than 3.5 kg m −3. The SAFER (Simple Algorithm for Evapotranspiration Retrieving) algorithm was used to retrieve ET, while for BIO estimations we applied the Monteith's radiation use efficiency model (RUE), then the water productivity based on ET was calculated (WP ET = BIO/ET). This was done to subsidize the rational irrigation and crop management, by using Landsat 8 images together with agrometeorological data during the year 2016 in the Camocim County, coastal zone of Ceará state. NWS radar overlays for 24-168 hours represent a total ending at 12UTC on or before the indicated gage-data date. NWS radar overlays for 1-12 hours are generated once an hour at the end of the hour. ![]() The current study aimed to determine and analyze actual evapotranspiration (ET) and biomass production (BIO), for dwarf coconut water productivity (WP) assessments. Precipitation gage data retrieved from NWISWeb. In the coastal areas of Northeast Brazil, coconut growers are replacing the tall varieties by the dwarf ones, following incentives for the coconut's water market. These tools were proven to allow detection of anomalies during different years, being of great potential to subsidize natural resources management, under the climate instability of semi‐arid environments. ![]() Modeling by using the MOD13Q1 reflectance product and weather data was confirmed as a promising tool for operational agroecosystem monitoring at a 16‐day and 250 m time and spatial scale, respectively. Anomalies on precipitation (P), actual evapotranspiration (ET), and biomass production (BIO) were noticed, when comparing the year 2017 and the long‐term period, but they occurred differently in natural vegetation and irrigated crops, being negative and positive, respectively. Remote sensing parameters and agrometeorological stations were coupled, involving Moderate Resolution Imaging Spectroradiometer (MODIS) images and weather data from 2003 to 2017. Algorithms were used for biophysical characterization and monitoring of agrometeorological standardized indices, in the agricultural growing areas of the semi‐arid region of northeast Brazil. The same was true in San Francisco and Oakland, which each collected nearly 4 inches of rain between Wednesday and Sunday, bringing the totals this season to roughly 7.5 inches. ![]()
