Oh merci je ne connaissais pas, je passais par pdsi, ce qui par moment est assez pénible 😅

Le grandi conquiste sociali degli anni 70 sono state ottenute collettivamente, per lo piu grazie al PC, il PSI, PDSI,... poi i primi attivisti performativi vollero metterci il cappello, facendoli diventare successi individuali,non di milioni di volontari. Da allora non si é piu ottenuto un granché.

SPP PWK Cilacap Tolak PDSI Digabung ke Elnusa, Khawatir Penguasaan Negara Berkurang
WARTABANYUMAS, CILACAP – Serikat Pekerja Pertamina Patra Wijayakusuma (SPP PWK) Cilacap menyatakan penolakan terhadap rencana penggabungan PT Pertamina Drilling Services Indonesia (PDSI) ke PT Elnusa Tbk. Ketua Umum SPP PWK Cilacap, Dwi Jatmoko, mengatakan pihaknya memahami kebutuhan efisiensi dan penataan struktur perusahaan, tetapi meminta agar kebijakan tersebut tidak berdampak pada berkurangnya penguasaan negara terhadap bisnis drilling yang dinilai strategis. “Kami tegas menolak jika penggabungan PDSI ke perusahaan terbuka berujung pada berkurangnya penguasaan negara atas bisnis drilling strategis,” kata Dwi, Rabu (9/9/2026). Menurut Dwi, rencana penggabungan tersebut tidak seharusnya hanya dilihat sebagai persoalan restrukturisasi korporasi karena menyangkut keberadaan aset, pengalaman, dan kemampuan strategis Indonesia di sektor hulu minyak dan gas.

Estimate PDSI value in GEE for a specific shapefile area
How can I estimate PDSI value in GEE for a specific shapefile area? I am having some problem in the code. var feature = ee.FeatureCollection(table); Map.addLayer(feature, {}, 'My Polygon'); var startDate = ee.Date('2005-01-01'); var endDate = ee.Date('2005-12-31'); // Load the necessary image collections var temperature = ee.ImageCollection("NASA/ORNL/DAYMET_V4"), precipitation = ee.ImageCollection("NASA/ORNL/DAYMET_V4"), elevation = ee.Image("USGS/SRTMGL1_003"); // Filter the image collections to the desired time range and region temperature = temperature.filterBounds(feature) .filterDate(startDate, endDate).select('tmax'); precipitation = precipitation.filterBounds(feature) .filterDate(startDate, endDate).select('prcp'); elevation = elevation.clip(feature); // Calculate the monthly temperature and precipitation averages var monthlyTemp = temperature.reduce(ee.Reducer.mean().combine({ reducer2: ee.Reducer.median(), sharedInputs: true })); var monthlyPrecip = precipitation.reduce(ee.Reducer.mean().combine({ reducer2: ee.Reducer.median(), sharedInputs: true })); // Calculate the water balance variables var tmax = monthlyTemp.select('tmax'); var pet = tmax.multiply(0.003 + 0.007 * elevation).subtract(0.26); var ppt = monthlyPrecip.select('prcp'); // Calculate the PDSI var pdsi = ee.Image().expression( '(((0.897 * (pet - ppt)) + 0.166 * ((pet - ppt) ** 1.5)) / ' + '(((12 * 0.897 * (pet - ppt)) / (tmax - 32)) + 1))', { pet: pet, ppt: ppt, tmax: tmax }).rename('pdsi'); var visParams = { min: -5, max: 5, palette: [ 'red', 'yellow', 'green', 'cyan', 'blue' ], value: 'pdsi' // Specify the name of the band to use for visualization }; Map.addLayer(pdsi, visParams, 'PDSI'); // Check for any errors or missing parameters print(pdsi);

Iceland Drilling Company and PDSI sign MoU
Iceland Drilling and Pertamina Drilling Services Indonesia have signed a memorandum of understanding (MoU), marking an important step in strengthening collaboration between the two companies in geothermal drilling services. This partnership reflects a shared commitment to exploring and developing new business opportunities, while combining the respective capabilities, expertise, and experience of both organisations. The signing ceremony was witnessed by the Director General of International Law and Treaties from the Ministry of Foreign Affairs of the Republic of Indonesia and the Ambassador of Iceland to Indonesia, highlighting the importance of international co-operation in supporting the energy transition and the sustainable development of geothermal resources. Through this collaboration, PDSI and Iceland Drilling aim to support sustainable business growth, expand opportunities in Indonesia and international markets, and contribute to the advancement of geothermal well construction. By combining Indonesia’s world-class geothermal resource potential with Iceland’s decades of geothermal drilling experience, the partnership creates a strong platform for innovation, knowledge sharing, and the future development of next-generation geothermal technologies, including the potential of superhot rock (SHR) resources. Indonesia and Iceland are uniquely positioned as global geothermal leaders. By working together, both companies can help unlock more renewable energy, strengthen energy security, and contribute to a...

Mapping over a reduceRegions command in Earth Engine
I have a feature collection of about 80,000 tiles, and I am trying to calculate the annual maximum drought severity index score for each tile using TerraClimate data. TerraClimate is an image collection, so I started by transforming it into a stack of images. var drought_M = ee.ImageCollection("IDAHO_EPSCOR/TERRACLIMATE").select("pdsi") .filter(ee.Filter.date('2000-01-01', '2012-12-31')); //This function creates a stack of images from the image collection function newCollectionToImage(collection){ var stack = ee.Image(collection.iterate(function(img, prev) { return ee.Image(prev).addBands(img); }, ee.Image(1))); stack = stack.select(ee.List.sequence(1, stack.bandNames().size().subtract(1))); return stack; } //This function renames the image collection bands var drought_M_rename = drought_M.map(function(img){ var y = ee.String(ee.Date(img.get('system:time_start')).get("year")); return img.set("year",y).rename(y); }); //Apply the function to create a stack of images var droughtImageStack = newCollectionToImage(drought_M_rename); I tried to use reduceRegions() to get the monthly score for each tile. var droughtImageStack = tchImg.reduceRegions(tiles, ee.Reducer.mean()); This works in the terminal, but when I try to export the dataframe as a csv, GEE returns the error: Error: User memory limit exceeded. I've been told before that image reductions become a lot more efficient when you map over the feature collection. I tried to use the basic intuition of how to map over a feature collection for reduceRegion() and attempted the following: var droughtTiles = tiles.map(function(feature) { return feature.set(droughtImageStack.reduceRegions({ reducer: ee.Reducer.mean(), geometry: feature.geometry(), scale: 10 })); }); But this map function returns an error: Required argument (collection) missing to function: Image.reduceRegions(image, collection, reducer, scale, crs, crsTransform, tileScale)... How can I adjust my mapping function to produce monthly tile means that export?

Large-scale ocean–atmosphere 🌊 variability drives this linkage across Asia—ofc, anthropogenic warming is pushing both regions beyond the range of natural variability over the last millennium: projected temps & circulation changes will increase frequency of extreme events & hamper predictability.

Holy crap. Back when I was doing my Master's thesis on PDSI and evapotranspiration rates impacting irrigation water required, these types of values didn't show up until my 2040s bracket.

Good work everyone.

Worst April drought in contiguous U.S. history: Palmer Drought Severity Index (PDSI) was the lowest on record for any April, at -7.56. The only worse drought conditions: March 2026 (PDSI of -7.85), and during the Dust Bowl months of July-August 1934 (PDSI of -8.09 and -8.42, respectively).

The Palmer Drought Severity Index (PDSI) shows shows dryness in shades of brown across much of the US, and some wetter areas in northern reaches of the US.
